FIPS: Add EDDSA public key validation.

FIPS: Add EDDSA public key validation.

EVP_PKEY_public_check() can be used by ED25519 and ED448 in order to
determine if the public key is a valid point on the curve.

The FIPS ACVP tests require public key validation tests.
See https://github.com/usnistgov/ACVP-Server/blob/master/gen-val/json-files/EDDSA-KeyVer-1.0/internalProjection.json

Note that this is NOT required to be called before EDDSA signature verification
since it is done internally.
