Subject: [PATCH] meson: Define MESA_DEBUG for latter usage

rationale:
DEBUG is easily conflict with third-party headers, for example LLVM https://github.com/llvm/llvm-project/issues/24002#issuecomment-1673922017
And amdcommon's addrlib

And according to https://github.com/llvm/llvm-project/issues/24002#issuecomment-1673922017
LLVM is already switched to LLVM_DEBUG, I think it's time for mesa switch to MESA_DEBUG for #ifdef DEBUG.
