[llvm-branch-commits] [ELF][AArch64][PAC][MTE] Handle Memtag globals for R_AARCH64_AUTH_ABS64 (PR #173291)

I've marked approved on my side as I think this is the obvious way for MTE and PAuthABI to coexist. The use case in the memtag ABI for an addend larger than 32-bits seems extremely unlikey. If there is a need for that we can work out another mechanism.
