This is a preparation for each input stream creating its own window. It
moves deleting the property from meta_x11_selection_input_stream_xevent
where it can run after the stream has been finalized to a spot where
the stream still exists. Use an error trap in case the property was not
set by the client, such as when the conversion failed.

The only currently known issue with allocating scanout buffers with
modifiers is memory constraints in multi head setups. Heuristics for
handling that are not implemented, but since it doesn't apply to
anything but i915, remove the other drivers from the deny list.
The other drivers had modifiers disabled to marginally increase the
chance of becoming scanout-able when allocated by Xwayland.

This significantly increases the chance of a fullscreen surface buffer
being scanned out instead of being painted via composition. This is
assuming the client supports the DMA buffer feedback Wayland protocol.

This API can be used to construct a MetaKmsUpdate with plane assignments
that in isolation will be tested against the current KMS state. How it
is tested depends on the KMS implementation; in the simple / legacy KMS
backend, the tests are identical to the current scanout requirements
(dimension, stride, format, modifiers, all must match), and with atomic
KMS, it uses the TEST_ONLY on a real constructed atomic mode setting

Whenever a surface is promoted as a scanout candidate by
MetaCompositorNative, it'll get a CRTC set as the candidate CRTC.
When a client asks for DMA buffer surface feedback, use this property to
determine whether we should send a scanout feedback tranche.

This ensures they remain perfectly smooth regardless of how the
dispatch time has been adjusted/optimized/delayed/jittered.

For example, dragging a window on a 60Hz monitor:
BEFORE
delta(time_us) = 17014μs
delta(time_us) = 15998μs
delta(time_us) = 17006μs
delta(time_us) = 16975μs
delta(time_us) = 16001μs
delta(time_us) = 17002μs
delta(time_us) = 17006μs
delta(time_us) = 16004μs
AFTER
delta(time_us) = 16667μs
delta(time_us) = 16667μs
delta(time_us) = 16670μs
delta(time_us) = 16667μs
delta(time_us) = 16669μs
delta(time_us) = 16668μs
delta(time_us) = 16664μs
delta(time_us) = 16674μs
Caveat 1: Because we don't know a "next presentation time" on the first
frame, the interval between the first and second frame will usually be
different to the subsequent steady interval. So this change increases the
jitter of just frame 2, but eliminates jitter thereafter.
Caveat 2: `clutter_frame_clock_schedule_update_now` schedules updates
earlier than `clutter_frame_clock_schedule_update`. This means potentially
you could get multiple frames targeting the same "next presentation time".
That doesn't really change here though - we're dispatching at the same
times as we used to and just giving timelines a better vsync-aligned
timestamp now.

The final tick of a timeline is >= its duration, but when using ticks that
are slightly in the future ("next presentation time") this means the final
tick will execute and complete the timeline up to one frame interval before
the timestamp of that final tick.
For the single clock test we now just check if the overall duration is
within one frame of the expected timeline duration.
The dual clock (switching) test needs a threshold of two frames because
starting each new clock creates a phase shift (error) of up to one frame.

We can't just run a single 'meson' command in the script as we need to
launch multiple long running processes inside the D-Bus session:
* The meson test invokation itself
* wireplumber
This was handled for the 'test' stages, but not for the 'dist' stage,
which as a result would fail due to wireplumber not being launched
causing any test using pipewire to timeout.
Address this by making run-tests.sh a more generic run-meson.sh that
launches wireplumber before running the actual meson command.

We're in the destructor, it's pointless to unset the userdata as we'll
never ever see a request being invoked with it ever again, since the
resource itself will be destroyed or marked as destroyed.

When rendering to a buffer that is not the stage view buffer, we can not
know where the buffer will be displayed on the screen. As a result we
also can not know what translation would need to be applied to culling.
This was causing glitches when the gnome-shell magnifier was applying
offscreen effects. ClutterOffscreenEffect causes MetaWindowGroup to be
rendered to an offscreen buffer at an offset, because it draws to a
slightly larger texture with an accordingly translated origin. This
translation then later is canceled out again when the offscreen buffer
is drawn. To meta_actor_painting_untransformed() however which only sees
the translation used when drawing to the buffer this looked like the
window group was being rendered at the offset. This then lead to
redraw_clip getting translated accordingly, resulting in wrong
coordinates used for culling.
Similarly this was leading to issues when taking area screenshots while
at 1x zoom.

Refresh rates >60Hz become ever more common. In order to allow users
to keep hight refresh rates when not running at a natively advertized
resolution, add common refresh rates to our fallback modes.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2189>
Right now we often add a duplicate fallback mode that's almost
identical to the native mode. This adds unnecessary clutter to
UIs, thus filter out such modes.
In order to keep the code small, use `MetaCrtcModeInfo` directly
instead of recalculating the values. And to keep consistency, do
the same in the loop above.
