ec: Add PPC64 vector assembly version of p521 field operations
Only field multiplication and squaring (but not reduction) show a
significant improvement. This is enabled on Power ISA >= 3.0.
On a Power 9 CPU an average 10% performance improvement is seen (ECHDE:
14%, ECDSA sign: 6%, ECDSA verify 10%), compared to existing code.
On an upcoming Power 10 CPU we see an average performance improvement
of 26% (ECHDE: 38%, ECDSA sign: 16%, ECDSA verify 25%), compared to
existing code.
