ml-dsa(fips): add power up signature self tests for ML-DSA-65

This added self tests for ML-DSA.  IG 10.3.A.15 requires known answer
tests for both signing and verify.  This adds them.

The signature generation is constructed to encounter all three of the rejection
loop tests that are relevant for ML-DSA-65.  The message has been generated
so that:

    * it fails the z_max rejection test on iteration one
    * it fails the r0_max rejection test on iteration two
    * it fails the h_ones rejection test on iteration three
    * it successfully generates the signature on iteration four

It is thus an optimal self test in terms of iterations and coverage.

Key generation self tests will be dealt with separately.
