Add EDDSA FIPS self tests.

Add EDDSA FIPS self tests.

See FIPS 140-3 IG Section 10.3.A Part 11
Indicates ECDSA requires a sign and verify test.
Note 11 states that HashEdDSA is not required to be tested if PureEdDSA is tested.
Note 12 indicates that both ED25519 and X448 need to be tested.

Since ED uses the oneshot interface, additional API's needed to be exposed to the
FIPS provider using #ifdef FIPS_MODULE.

Changed ED25518 and ED448 to use fips=true in the FIPS provider.
Updated documentation for provider lists for EDDSA.
