Unlike other subsurface state, placement operations need to get
applied in order. As per spec:
```
Requests are handled in order and applied immediately to a pending
state. The final pending state is copied to the active state the
next time the state of the parent surface is applied.
```
Having placement operations being part of the subsurface state
makes it difficult to support arbitrary orderings. Make them
part of the parents surface pending state instead.

Some events such as the proximity one requires a device to be set before
we process them, so ensure we process the event details after we've
added the device to the seat.
This may lead to handle a device-removed signal before the clutter event
but it's anyways not different from what we did before commit 012c0a18

The CallyStage objects lifetime is tied to the stage, so if we add a
weak pointer to it, we won't be able to remove it, as we would try to do
so not until the stage itself is being disposed, at which point removing
it fails. However, not removing it will make the stage try to clean up
the weak refs, and since it does this more or less directly after
freeing the cally stage, it ends up writing NULL to freed memory,
causing memory corruption.
Fix this by avoiding adding the weak pointer when that pointer is to the
stage.

MetaInputSettings unref:ed the seat on destruction, but it never ref:ed
it on construction, meaning it "stole" the reference from the rightful
owner. Make MetaInputSettings less of a thief.

XIQueryPointer allocates the button state mask that we were leaking in
some places. We need to manually free this, because there is no XI
function that would do this for us.

In case the shell ignores or can't accept the restart request we should
hide the message that has been just requested to be shown.
As per ::show-restart-message signal documentation, this has to be done by
emitting the signal with a NULL message.
So follow the API properly in such case

In non-systemd managed session we are unable to start services on
demand. Instead, gnome-session will start everything at login time,
including any X11 related service (i.e. gsd-xsettings).
However, in order to start gsd-xsettings, Xwayland needs to be started
already. Otherwise it will connect to GNOME_SETUP_DISPLAY and login will
hang at that point.
Fix this by detecting whether mutter is running in a systemd unit. If it
is, we assume that we are systemd managed and the machinery to start the
services works fine. If not, we assume that the session management may
unconditionally try to start X11 related services and Xwayland must be
started in order to not block this.

On Wayland MetaInputSettings is part of the input thread. Connecting
a GSettings binding to the default ClutterSettings could result in the
change notification being emitted on the input thread. This then could
end up triggering the same handler from two different threads at the
same time. In the case of the ClutterText layout cache it was attempting
to unref the same layout twice, leading to a crash.
This can be avoided by simply removing the GSettings bind. This does not
cause changes to this setting to be missed by ClutterSettings because it
itself already sets up a bind.

When deciding if `configure` event should be sent,
`meta_window_wayland_move_resize_internal` compares requested window size
with `window->rect` size. However, `window->rect` is only updated when `commit`
is received. So the following sequence produces incorrect result:
1. a window initially has size `size1`
2. `move_resize_internal` is called with `size2`. `configure` is sent
3. `move_resize_internal` is called with `size1` to restore original size,
but `commit` for `size2` haven't arrived yet. So `window->rect` still has size
`size1`, and thus new `configure` is not sent
4. `commit` for `size2` arrives, window changes size to `size2`
Expected window size in the end: `size1`
Actual: `size2`
To fix the issue, take size from pending `configure` events into account.

With the surfaceless mode in the headless backend, it's now possible to
initiate the headless mode without any mode setting devices, or render
nodes, without any special CI runner privileges.
The native backend tests include screen cast tests, so make them
possible to run by starting pipewire. Testing shows that enabling audio
support (pulseaudio & jack compat layers) makes the tests dead lock and
eventually timeout, so disable those features for now.

This eliminates the need for any render node or device nodes, thus can
be used without any graphics hardware available at all, or with a
graphics driver without any render node available.
The surfaceless mode currently requires EGL_KHR_no_config_context to
configure the initial EGL display.
This also means we can enable the native backend tests in CI, as it
should work without any additional privileges.

Tests that creating and starting a virtual screen cast monitor works,
and that at least one one buffer is processed.
Currently the content of the buffer isn't checked more than it can be
mmap():ed. Only MemFd buffers are tested for for now, as DMA buffers
would need a surfaceless EGL context to check properly.
