d8a61edca0 gtk4: Add scaling-filter and use-scaling-filter properties
The property is added under the gtk_v4_10 feature because it requires
GTK 4.10.

This is equivalent, but will be needed for the scaling filter support.

9971f71e94 gtk4: Always draw a black background behind the video frame
This makes sure that there is the same background behind the frame, no
matter if black borders have to be added or not. Without this a frame
that has transparency would change rendering depending on the layout.

803550111a gtk4: Improve handling of RGBA GL textures in GTK
GTK 4.14 comes with a new GL renderer that does not support GL shader
nodes anymore, so the conversion from non-premultiplied alpha to
premultiplied alpha has to happen differently.

For GTK 4.14 or newer we use the correct format directly when building the
texture, but only if a GLES3+ context is used. In that case the NGL renderer is
used by GTK, which supports non-premultiplied formats correctly and fast.

For GTK 4.10-4.12, or 4.14 and newer if a GLES2 context is used, we use a
self-mask to pre-multiply the alpha.

For GTK before 4.10, we use a GL shader and hope that it works.

4ad101b53b Use once_cell crate directly again
The glib crate does not depend on it anymore and also does not re-export
it anymore.

Also switch some usages of OnceCell to OnceLock from std.

c237cf2c34 gtk4: Premultiply alpha in GL textures
GTK expects GL textures to have premultiplied alpha. The ones we get
from GStreamer don't, leading to incorrect rendering of semitransparent
frames.

GTK 4.12 gained an API to set a different GL texture format, but it
won't help for older GTK versions. Plus, at the time of writing, it
causes a very slow download/upload path in GTK.

So, use a GTK GL shader node to premultiply the alpha without leaving
the GPU.

8aa5125d5b gtk4: Refactor and simplify GL context handling
Create a single, global GDK GL context and the corresponding GStreamer
GL display and wrapped GStreamer GL context when initializing the first
sink and continue using that for all further sinks.

Additionally, don't create a full GStreamer GL context inside the sink
but only distribute the wrapped GL context in the pipeline so that
elements that actually need a full GL context can create one that is
sharing with that one. The sink itself does not need a full GStreamer GL
context.

Then inside the sink check that any GL memory that arrives was created
by a GL context that can share with the wrapped GDK GL context and only
then use it.

And lastly, use the correct GL contexts for a) creating a sync point and
b) actually waiting on it.
