Add a relocation for R_AARCH64_ABS32 in ObjectFileELF
Summary:
.rela.debug_info relocations are being done via
ObjectFileELF::ApplyRelocations for aarch64. Currently, the switch case
that iterates over the relocation type is only implemented for a few
different types and `assert(false)`es over the rest.
Implement the relocation for R_AARCH64_ABS32 in ApplyRelocations
