BaseTools/PeCoffLib: handle EFI_IMAGE_REL_BASED_DIR64 in generic code 

Relocations of type EFI_IMAGE_REL_BASED_DIR64 are handled in exactly
the same way on all 64-bit machine types (IPF, X64 and AARCH64).
So move the handling of this type to the generic part of the relocation
routine PeCoffLoaderRelocateImage ().
