arc: Add new ARCv3 ISA to BFD.
The new Synopsys's ARCv3 ISA is capable to run either 64-bit or
32-bit ISA. The new 32-bit ISA is not compatible with the old
Synopsys ARCv1/ARCv2 ISA, however, it retains a lot of common
concepts. Thus, this patch is reusing the old ARC BFD backend and
adds the necessary bits for the new architecture in a similar way as
it is done for RISCV backend.
