Currently, we don't handle too well the removal of a MetaWaylandEventInterface
during meta_wayland_event_interface_invalidate_all_focus(), since the
MetaWaylandEventInterface may be freed at an intermediate point in that function
while handling the focus change for all input devices.
Turn this invalidate_all_focus() function into a MetaWaylandInput method, and
always ensure to use the currently effective MetaWaylandEventInterface when
resetting the focus for each device.
This fixes the situation through handling reentrancy naturally, a focus
sync (say, triggered by a grab) would reset a device focus (say, pointer), which
would remove an event interface (say, a pointer constraint), which would
invalidate_all_focus() again underneath using the new effective
MetaWaylandEventInterface. When that is done, the initial invalidate_all_focus()
call would re-apply the same focus to the same currently effective
MetaWaylandEventInterface, resulting in a no-op for the remainder of the function.

Even though the logical focus is typically business that only the
MetaWaylandEventInterface mechanism minds about, there are some pointer
subsystems that want to look this up, as opposed to the current surface.
Add a getter to make this easier, without struct peeking.

This also removes some g_return_if_fail's because the test suite expects
to be able to create arbitrary KmsUpdates even if they don't make sense
for the real state. We just get lucky that the test suite isn't
constructing updates with color space and hdr changes, yet.

Currently querying support for some output features is done partially
through the OutputInfo and partially via KMS CRTC and Connector objects.
Let's be consistent and use OutputInfo always which works with all
backends and backend types.

We're currently pretending the gamma LUT has another size. This becomes
a problem when we try to reset the LUT to passthrough, create an
identity LUT for it and it has a size that the kernel doesn't accept.
We do track the size and have utility for creating the LUTs, so let's
just use them.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3552>
The kernel doesn't let us set gamma to passthrough with the legacy API
so we have to trick a bit and create an identity LUT, and also when we
read the KMS state, detect when an identity LUT is active.

The frame size_allocate() will set it correctly once show() is called by
the window tracker.
This is less code and also help reduces the chance of a brief visual
glitch in fullscreen games during startup. If the window is initially
still decorated the gray area would still show up until the next redraw,
which due to loading times can take a while.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3608>
Relying on the content size_allocate() to determine the content position
can fail in situations where the position of the content has changed,
but not its size.
This happens for example when the window initially is sized fullscreen
height + headerbar height while not considered fullscreen yet. Then when
the window is resized to just the fullscreen height and marked as
fullscreen, the content size has not changed and size_allocate() is not
called on the content. Thus the previous position which assumes the
presence of a headerbar still applies. As a result the window is shifted
down, revealing a headerbar sized area showing the gtk window background
color.
This issue can be avoided by using the frame's size_allocate(), which
gets called in response to all relevant events, such as any headerbar
size changes, headerbar visibility changes, window resizes and
fullscreen status changes.

Allows to mark a wayland client window as a DOCK window. The reason for
this is that in Gala (elementary OS's window manager) we would like to
continue using GTK apps as panel and dock on wayland.

Assigning the corresponding stack layer of DOCK windows is currently X11
specific, because there is no way for wayland clients to set the DOCK
window type. This is about to change, so move the code to the generic
layer handling.

adaita-icon-theme cleaned up its cursor set, and now only provides
names defined by GTK/CSS. Update the cursor-hotplug test to not
use legacy cursor that will fail with a recent cursor theme.

meta_window_update_monitor() can emit "::highest-scale-monitor-changed",
and we connected to that signal right before. Let's avoid calling
meta_wayland_surface_notify_highest_scale_monitor() twice and move the
g_signal_connect() for that signal and the initial call to
meta_wayland_surface_notify_highest_scale_monitor() to happen after
meta_window_update_monitor().

Turns out there is a better solution: Almost always, MetaWindow already has
an idea on which monitor it will be, even if it isn't positioned yet. Since
the last commit we're now using that monitor for setting the
highest-output-scale of the window, so this fallback is no longer necessary.
While we could keep this fallback around and also return a valid scale in
case the surface is not even mapped yet, this means we report fractional
scale twice for new surfaces: Once from
wp_fractional_scale_manager::get_fractional_scale() (here we'll enter the
fallback), and a second time (this time with correct scale) right after
creating the MetaWindow.
Note that wp_fractional_scale_v1 doesn't specify that a preferred_scale
event must be sent immediately after
wp_fractional_scale_manager::get_fractional_scale(), so we can safely remove
the fallback.
This reverts commit 8cfbdb4313.

MetaWindow always tries to have a main monitor: If the frame rect is empty
and the window has not been positioned, in meta_window_constructed() we fall
back to asking the backend for the current monitor, and in
meta_window_wayland_update_main_monitor() we fall back to
meta_window_find_monitor_from_id(), which then falls back to the primary
monitor.
In general this means that window->monitor is always set as long as there is
a monitor around.
For getting the highest-scale-monitor the window is on, we currently rely
completely on the frame rect. If the frame rect is empty, we set the
highest-scale-monitor to NULL. Since we usually know though which monitor
the window is, or will be on, and window->monitor is even set to that, we
can just fall back to window->monitor for the highest-scale-monitor.
This makes sure ::highest-scale-monitor-changed is emitted right after the
window is created, and it's set to the correct monitor that the window will
be on. This in turn means that we can send a correct wp_fractional_scale
fraction_scale event to clients right away.
