Packaging: Virtual package for libllvm (#27200)

Browse source 
Add an abstraction around libllvm to allow libllvm
providers to be specified for all packages.

This is targeting allowing mesa to build against
llvm-amdgpu or intel-llvm or llvm or any other
custom llvm variant that arises for specific GPU
toolchains
