ftruncate() allocates disk space lazily. If the disk is full and it is
unable to allocate disk space when accesed via mmap(), it will crash
with a SIGBUS.
Switch to posix_fallocate(), which ensures disk space is allocated
otherwise it fails if there isn't enough disk space. The disk cache
won't be enabled in this case.
For normal cases, a small increase in disk usage as the 1.3MB index
file will be fully allocated when initialized now.
fallback to ftruncate() if posix_fallocate() isn't found.

The mediump lowering tests are important for poking at the lowering pass
behavior, since you can't really assert the behavior in any given driver,
given that the GLSL spec allows any mediump op to be done in highp.
But, in hacking on mediump lowering, I wanted several things that the old
test couldn't do:
- Be able to assert about the actual NIR code we expect to generate for a
hypothetical driver (important if other compiler stages might do invalid
transformations like eliminating highp temps, or if we were to move the
lowering after GLSL IR)
- Run faster (gtest unit tests rather than python forking off the standalone
glsl compiler per testcase).
- Express expectations with a lot less escaping of typical syntax.
- High-quality logs for displaying failures.
This new test does all of that, I think, though I haven't converted all of
the unit tests over yet. In converting, I dropped some of the
combinatorial explosion for float/int variations, instead only doing so
when it gets at some different code path (default precision flags). I've
also included some new tests I wrote in the process of writing my proposed
gl_nir mediump lowering.
Even if the conversion isn't complete, getting these tests to run faster
is probably a good idea on its own, for anyone iterating running Mesa's
unit tests (80 tests in 25ms, compared to 109 tests in 1.5s!).

The plan is to compile all the Xe files but in run time it will fail
to detect the KMD loaded and it will fall back to software
rendering(if build).
Compiling Xe files makes sure newer commits don't break Xe even if
developers don't have Xe enabled in their build folder.

Now that turnip can support multiple kernel-mode drivers in a single
build, re-work the meson option to have a single list of KMDs, rather
than special options to enable kgsl for turnip or virtio for gallium.
It is temporarily a bit awkward as gallium does not yet support kgsl
and turnip does not yet support virtio. But both of those are planned
or in-progress, so long term a single list is the most sensible option.
TODO freedreno/drm support to build with only virtio support.

There is no UVD and the mpeg2 shader-based decoding is broken and doesn't
lead to CPU savings anyway. VDPAU output works, but there is no real
benefit so just disable VDPAU altogether so we can clean the backend a
bit and also open a way to potentially drop the mpeg2 deconding altogether
from the fronted.

Only code that cares about Vulkan WSI should get the corresponding
arguments passed. Otherwise, the Vulkan headers might end up including
other headers that we don't have the correct dependencies passed for.
So let's give those a dedicated variable, and only pass that where it's
actually needed.

We first do an incomplete check for whether the linker supports
--gc-sections, then potentially add C and C++ arguments assuming that it
works, then later do a complete check to see if it actually works and
use --gc-sections. This means we can end up putting functions and data
in separate sections when we can't gc them.
Combine the checks, do less work, and be more accurate.
