  [LLD][COFF] PR49068: Include the IMAGE_REL_BASED_HIGHLOW relocation base type when the machine is 64 bits and the relocation type is ADDR32

The COFF driver produces an ABSOLUTE relocation base for an ADDR32
relocation type and the system is 64 bits (machine=AMD64). The
relocation information won't be added in the output and could
produce an incorrect address access during run-time. This change
set checks if the relocation type is IMAGE_REL_AMD64_ADDR32 and
if so, adds the relocated symbol as IMAGE_REL_BASED_HIGHLOW base.
