gnu: mesa: Update to 24.2.2.

Note the clang input for mesa was in inputs for aarch64-linux but more
generally in native-inputs for mesa-opencl.  Moved to native-inputs for
all (mesa does not retain a reference to clang).

* gnu/packages/gl.scm (mesa): Update to 24.2.2.
[inputs]: Move clang-18 when building for aarch64-linux to ...
[native-inputs]: ... here for all architectures.  Add python-ply, and
python-pyyaml.  Use libclc for all architectures.
(mesa-opencl)[inputs, native-inputs]: Remove fields.
* gnu/packages/python-xyz.scm (python-pyyaml, python-ply): Add a comment about
being dependencies of mesa.
