We want to run those tests in VKMS later with the same reference image.
To make the tests as close to each other as possible we use the same
resolution for the VKMS and the virtual output which is 640x480.

This test currently only works because the monitor has the same width
and height. Generalize it to arbitrary monitor sizes by taking into
account that width and hight are swapped for some rotations.

Most tests use the draw_surface function to draw a solid color to a
surface. This moves it from the shm-only path to WaylandBuffer which
makes all of those tests usable via dma-buf.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3350>
The custom drawing requires adjusting the test. Instead of poking at
memory directly, we can just draw a color at certain coordinates which
makes it independent of the pixel format used.

It abstracts away the kind of buffer so clients can be tested with both
shm and dma-buf paths. We'll make use of it in the future by adding the
wayland tests to the TTY and KVM test suits.

When capturing the view we have to make sure the stage is actually
updated. In direct scanout mode the stage is unmodified and we can't
find the content we want to test.
Currently the ref-tests are all running on non-native setups where
direct scanout is impossible but we will change that soon!

Some actors have a well-defined layout manager other than FixedLayout.
If they do, we can handle the layout manager creation at the
ClutterActor instantiation, like GTK does for widget layout managers.

We will also require GL_OES_texture_half_float and GLES 3.0 to enable
COGL_FEATURE_ID_TEXTURE_HALF_FLOAT. This gives us float types and makes
it possible to read pixels from framebuffers with internal floating
point formats (into float, half is never supported).

This implementation is copied from mesa.
It uses x86_64 assembler on CPUs where it's supported, otherwise falls
back on a software implementation (cogl-soft-float.c). It's intended to
be used for packing and unpacking f16 format bitmaps.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3441>
The implementation comes from mesa, which came from Berkeley SoftFloat
3e Library.
The software float implementation will be used to convert from and to
half floating point pixel format bitmaps, when no the CPU isn't capable
of the conversion.

The type of the intermediate medium for storing pixel channels is
changed from "is 8 or 16 bit" to an enum, and switch cases. This doesn't
add support for anything, but will make adding a "float" medium type
less intrusive.

There is no internal fp16 format which has no alpha which means we would
get garbage alpha when reading the framebuffer directly. We have to use
the packing/unpacking to always get the alpha of 1.

Which gltype and glformat are allowed for a given gl framebuffer depends
on the internal gl framebuffer format. Either the format we want to read
into matches the gltype, glformat and doesn't need CPU packing from
another format or we have to use a tmp buffer with a format that matches
the GL requirements.

Sometimes it's useful to combine the description from multiple places.
For example, a subsequent commit will add the output name as the first
thing to the frame clock span descriptions, leaving the rest of the
description with complex checks unchanged.

Tracy can filter its statistics by user text, in our case by span
description. It's useful to filter by actor type and name, and not so
much by the pointer. So, remove it, and also reduce the amount of
punctuation.
