mesa: fix dependencies and always prefer LLVM subproject

Make sure build dependency to mesa/host is set for x86 and x86/64 builds,
add missing dependency on Python ply and make sure to always prefer LLVM
subproject to avoid picking up LLVM from the build host (which may not
match SPIR-V converter tool version).
