meson in mesa no longer uses WANT_LLVM_RELEASE and LLVM_CONFIG so drop
those. Instead, copy the llvm-config binary into the target sysroot which
allows the paths to be relocated to the target in question. This should allow
the llvm patch for YOCTO_ALTERNATE_EXE_PATH to be dropped assuming nothing
else relies upon it.
