  [PAC][lld][AArch64][ELF] Support signed GOT

Support `R_AARCH64_AUTH_ADR_GOT_PAGE`, `R_AARCH64_AUTH_GOT_LO12_NC` and
`R_AARCH64_AUTH_GOT_ADD_LO12_NC` GOT-generating relocations. For preemptible
symbols, dynamic relocation `R_AARCH64_AUTH_GLOB_DAT` is emitted. Otherwise,
we unconditionally emit `R_AARCH64_AUTH_RELATIVE` dynamic relocation since
pointers in signed GOT needs to be signed during dynamic link time.
