When we use gbm together with the NVIDIA driver, we want the EGL/Vulkan
clients to do the same, instead of using the EGLStream paths. To achieve
that, make sure to only initialize the EGLStream controller when we
didn't end up using gbm as the renderer backend.

This is more in line with the protocol, and allows us to remove some
awkward code that tries to "combine" different metadata from different
monitors into one, which sometimes meant picking an arbitrary "main"
monitor, or "and" metadata together to find a common ground.

Before we first created the MetaWaylandCompositor instance, which would
repare Clutter/Cogl so they could initialize and turn on Wayland display
server features, then later to initialize the rest. Now that part is
done by the Wayland infrastructure itself, so we don't need the early
initialization. Simplify things a bit by centralizing it all into a
single meta_wayland_compositor_new() call.

As with the compositor type enum, also have the X11 display policy enum,
as it's also effectively part of the context configuration. But as with
the compositor type, move it to a header file for enums only, and since
this is a private one, create a private variant meta-enums.h.

We first initialized the Wayland infrastructure, then the display, but
on shutdown, we first teared down the Wayland infrastructure, then the
display.
Make things a bit more symmetric and tear down the display before
Wayland. This however means we need to tear down some things Wayland a
bit earlier than the rest. For now this is a separate function, but
eventually, it can be replaced with a signal shared by the backend's
'prepare-shutdown' signal.

This way we can initialize without having any way to retrieve it via
some global variable. This isn't needed now, but will be once Wayland
infrastructure initializiation is done in a single step.

This will allow us less awkward startup, where previously we had to
pre-initialize Wayland very early so Cogl could bind the Wayland display
when it initialized. Move things around so we bind the Wayland EGL
display when initializing the rest of Wayland infrastructure.

We initialize, but might not start, e.g. when a test case just needs a
backend and doesn't start mutter. When cleaning up, we'll still try to
clean up Xwayland integration, and this commit handles cleaning up
without having made the mess.

The presentation-time protocol allows surfaces to get accurate
timestamps of when their contents were shown on screen.
This commit implements a stub version of the protocol which correctly
discards all presentation feedback objects (as if the surface contents
are never shown on screen). Subsequent commits will implement sending
the presented events to surfaces shown on screen.

One for the public channel, and one for the private maintainance
channel. Use the public one for test clients, otherwise tests become
flaky, and the private one for MetaX11Display.

Since we schedule frames for each stage view seperately now, surfaces receive
frame callbacks for each stage view they are visible on.
Only emit frame callbacks for the primary stage view.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1468>
Replace the default master clock with multiple frame clocks, each
driving its own stage view. As each stage view represents one CRTC, this
means we draw each CRTC with its own designated frame clock,
disconnected from all the others.
For example this means we when using the native backend will never need
to wait for one monitor to vsync before painting another, so e.g. having
a 144 Hz monitor next to a 60 Hz monitor, things including both Wayland
and X11 applications and shell UI will be able to render at the
corresponding monitor refresh rate.
This also changes a warning about missed frames when sending
_NETWM_FRAME_TIMINGS messages to a debug log entry, as it's expected
that we'll start missing frames e.g. when a X11 window (via Xwayland) is
exclusively within a stage view that was not painted, while another one
was, still increasing the global frame clock.
Addititonally, this also requires the X11 window actor to schedule
timeouts for _NET_WM_FRAME_DRAWN/_NET_WM_FRAME_TIMINGS event emitting,
if the actor wasn't on any stage views, as now we'll only get the frame
callbacks on actors when they actually were painted, while in the past,
we'd invoke that vfunc when anything was painted.

Instead of going via MetaCompositor to know about when we updated
(confusingly named post-paint), use the new stage signal directly.
Note that this doesn't change the time frame callbacks are dispatched;
it's still not tied to actual painting even though it seemed so before
given the function names.

Move Wayland support (i.e. the MetaWaylandCompositor object) made to be
part of the backend. This is due to the fact that it is needed by the
backend initialization, e.g. the Wayland EGLDisplay server support.
The backend is changed to be more involved in Wayland and clutter
initialization, so that the parts needed for clutter initialization
happens before clutter itself initialization happens, and the rest
happens after. This simplifies the setup a bit, as clutter and Wayland
init now happens as part of the backend initialization.

Instead of having everything clumped at MetaWaylandDataManager,
split the primary selection to its own struct. This manager is
handled separately from wl_data_device_manager and other selection
managers, so they would be able to interoperate between them, even.

This is used by GDK and the X11 bits, but may also be used for
other initialization services we might need to run along with
Xwayland initialization.
However, as the -initfd argument in Xwayland is a fairly new
feature, add some meson build-time checks so that the feature
is handled transparently while allowing to explicitly set/unset
it.

Before this commit, sudo x11-app, e.g. sudo gvim /etc/some-file, fails
when running a Wayland session. Where as doing this under a "GNOME on Xorg"
session works fine. For a user switching from the Xorg session to the
Wayland session, this is regression, which we want to avoid.
This commit fixes this by creating and passing an xauth file to Xwayland when
mutter starts it. Just like gdm or startx pass a xauth file to Xorg when they
start Xorg.

As with the commits earlier, this also adds const qualifiers where
expected. However, the const variables are casted to non-const variants
so they can be passed to glib functions that take non-const variants but
expect const-like input.
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
This protocol supersedes the internal gtk_text_input protocol that
was in place. Functionally it is very similar, with just some more
verbosity in both ways (text_change_cause, .done event), and some
improvements wrt the pre-edit text styling.
One of the current limitations of EGLStreams is that there's no way to
resize a surface consumer without re-creating the entire stream.
Therefore, while resizing, clients will send wl_surface::attach requests
so the compositor can re-create its endpoint of the stream, but no
buffer will be available actually. If we proceed with the rest of the
attach operation we'll be presenting an empty buffer.
In order to fix this, a separate wl_eglstream_controller protocol has
been introduced that clients can use to request a stream re-creation
without overloading wl_surface::attach for that purpose.
This change adds the required logic to create the corresponding
wl_eglstream_controller global interface that clients can bind to.
Whenever a client requests a stream to be created, we just need to
create and realize the new EGLStream buffer. The same buffer resource
will be given at a later time to wl_surface::attach, whenever new
content is made available by the application, so we can proceed to
acquire the stream buffer and update the surface state.

Instead of scheduling a meta_later, keep track of the unassociated
windows, and look for matches as soon as the MetaWaylandSurface is
created on our side.
This will ensure the surface is given the Xwayland role before receiving
the first wl_surface.commit.
This commit moves out non-core wl_surface related code into separate
code units, while renaming types to fit a common scheme. The changes
done are:
* ClutterActor based surface roles built upon
MetaWalyandSurfaceRoleActorSurface. This object has been renamed to
MetaWaylandActorSurface and related functionality has moved into
meta-wayland-actor-surface.c.
* The code related to roles backed by a MetaWindow (i.e. built upon
MetaWaylandShellSurface) was moved into meta-wayland-shell-surface.c
* The majority of subsurface related code was moved into into
meta-wayland-subsurface.c and the object was renamed
MetaWaylandSubsurface.
