in nvk_physical_device.c).

Add a new MESA_LOG_PREFIX environment variable that allows fine-grained
control over log prefixes in file logger output on Linux. The variable
accepts a comma-separated list of options:
- "tag": include the tag prefix (e.g., "MESA:")
- "level": include the level prefix (e.g., "info:")
By default, both tag and level are included. Users can customize the
prefix by setting MESA_LOG_PREFIX to any combination (e.g., "tag",
"level", "tag,level", or empty string for no prefix), making the output
more flexible and readable for different use cases.
Other loggers (syslog, Android logcat, Windows debugger) are unaffected
and continue to include tag and level information as appropriate for
their format.

I routinely don't update the docs because the build (hawkmoth in
particular) is a pain. The prior instructions almost worked, except that
on Debian you need to use a venv (which is a good idea to do for py3-clang
as well for reproducibility, anyway), and the versions that were listed
didn't actually run any more due to a revoked dependency.

Setting MESA_VK_VALIDATE_SHADER_BINARIES will cause the shader code to
round-trip every shader through [de]serialize and only ever use the
deserialized version. This catches bugs where the driver may drop
things in the [de]serialization process. It also deserializes the new
shader again and compares it against the original to ensure that
deserialize -> serialize is idempotent.

This binary that perfetto builds automatically launches traced and
traced_probes, doesn't need tmux installed, doesn't need you to know tmux
ui, and doesn't need the tmux helper script hacked to not call the wrong
arch's ninja if you cross compiled.
Also, it's silly to send people into an explanation and links to docs,
when we have the instructions they actually want below.

This change adds the minimum support for VK_EXT_device_memory_report,
which only reports device memory events at this point. We can make it
more useful later (like what's done in ANV) if desired by some tools.

NIR+ACO is the best SSA-based shader compiler for AMD GPUs that exists.
There are many reasons why NIR+ACO is better than LLVM, and I have a long
list that I've collected over the years, but the major ones are better GPU
performance (faster GPU memory access thanks to better clauses and
scheduling, a lot less SGPR/VGPR spilling, better loop support, slightly
smaller shader binaries), 8x lower shader compile times, and smaller memory
footprint of the IR.
It also shows that NIR is a mature SSA-based shader compiler that helps
drivers generate optimized code very quickly.
And most importantly, radeonsi has slightly better Viewperf performance
with NIR+ACO than LLVM, and that's difficult to ignore.

Add documentation describing Android system property usage in Mesa. For
example, how environment varible names are translated by
os_get_option(), how to get/set values, and corresponding example
commands.
A new section is added to doc/envvars.rst which points to the full
details within the new "Android System Properties" section in
docs/android.rst.

These extensions are implemented in shared Vulkan/WSI code and
not driver specific. A Vulkan driver just needs to support
VK_KHR_timeline_semaphore, which Honeykrisp already supports
since its inclusion into Mesa.

For platforms that don't have native float64 support, skip the
arithmetic and clustered ops. While they would work, the lowering
for float64 for those increase significantly the shader for some
