This patch implements two most commonly used Global Offset Table relocations in ELF/AARCH64: R_AARCH64_ADR_GOT_PAGE and R_AARCH64_LD64_GOT_LO12_NC. It implements the GOT table manager by extending the existing PerGraphGOTAndPLTStubsBuilder. I brought a lot of code from Macho/ARM64 backend's GOT manager and it looks very possible to unify them to generic aarch64 got table manager.

I thought it's better to unify them in the later patch to focus changes on ELF backend, but I can do it in this patch if that's preferred.
