[LD][AARCH64]Add group relocations to create PC-relative offset.
This is a patch to add linker support for group relocations to create a
16, 32, 48, or 64 bit PC-relative offset inline.
The following relocations are added along with the test cases:
BFD_RELOC_AARCH64_MOVW_PREL_G0, BFD_RELOC_AARCH64_MOVW_PREL_G0_NC,
BFD_RELOC_AARCH64_MOVW_PREL_G1, BFD_RELOC_AARCH64_MOVW_PREL_G1_NC,
BFD_RELOC_AARCH64_MOVW_PREL_G2, BFD_RELOC_AARCH64_MOVW_PREL_G2_NC,
BFD_RELOC_AARCH64_MOVW_PREL_G3.
