[PATCH v4 0/9] mesa: upgrade to 25.0.2

[Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com>]

libclc is required in order to build Intel drivers in Mesa 24.1 and
later. Thus OE-Core is currently locked to the 24.0.x branch, which is
no longer maintained, having last release in June 2024.

A clean solution is to package Clang, then use it to build libclc and
SPIRV-LLVM-Translator (required for Mesa OpenCL support). However
creating proper recipes for Clang is a long process (ongoing by Khem
Raj).

This patchset attempts to solve the issue in a simpler way: by building
libclc and SPIRV-LLVM-Translator together with the LLVM. This way we
don't have to create target Clang recipes, there is no extra toolchain
to support, etc. Clang binaries are creted as a part of the build
process (in order to support building target packages), however it only
hits the LLVM sysroot-native and is only used by the LLVM target build.

Future work by Khem (once Clang is properly supported in OE-Core) should
allow us to create proper recipes for libclc and spirv-llvm-translator
and drop them from the llvm / clang recipe.

I think this approach provides a good balance between OE-Core being
stuck with the outdated Mesa release and being able to upgrade it,
bringing support for new hardware.

Last two patches of the series bring in RustiCL support, a new OpenCL
implementation within Mesa. They are optional for the sake of the
upgrade and can be dropped if there is any issue with those. RustiCL
support is mostly compile-tested at this point.

Changes in v4:
- Fixed QA issues reported against lib32-mesa-megadriver (Richard)
- Removed release notes link from the mesa's commit message (Alexander)
- Added link to the rust.bindgen() issue to RustiCL-related
  cross-compilation patch (Alexander)
- Renamed 'spirv' PACKAGECONFIG option to 'spirv-llvm-translator' in
  order to be more precise
- Link to v3: https://lore.kernel.org/r/20250329-mesa-25-v3-0-f4d0328eb867@oss.qualcomm.com

Changes in v3:
- Dropped llvm/fix-native-compilation.patch and
  llvm/0001-cmake-modules-CrossCompile-pass-SPIR-V-headers-path-.patch
  in favour of installing prepare_builtins into the sysroot, dropped
  corresponding EXTRA_OECMAKE params
- Dropepd -DCLANG_TABLEGEN from llvm's EXTRA_OECMAKE
- Enabled llvm-config wrapper for nativesdk too, fixing QA errors for
  nativesdk-mesa
- Added --libdir handling to llvm-config, dropping the need for
  mesa/0001-meson-use-target-path-for-Clang-libdir.patch
- Dropped extra LIBCEXTENSION from BINDGEN_TARGET, it is already a part
  of TARGET_OS
- Expanded commit messages to explain the patches
- Link to v2: https://lore.kernel.org/r/20250327221807.2551544-1-dmitry.baryshkov@oss.qualcomm.com

Changes in v2:
- Dropped YOCTO_ALTERNATE_LIBDIR patch
- Reworked mesa / LLVM integration to always use get_option('libdir')
- Reenabled AMD Vulkan driver (got disabled because of c&p error)
- Moved mesa-clc options to the libclc PACKAGECONFIG to fix several
  build errors
- Link to v1: https://lore.kernel.org/r/20250327135520.3920189-1-dmitry.baryshkov@oss.qualcomm.com/
