cr50: update FIPS module based on operational testing findingsstabilize-14498.B-cr50_stabstabilize-14496.B-cr50_stabfirmware-brya-14505.B-cr50_stabfirmware-brya-14505.71.B-cr50_stab

1. ECDSA pair-wise consistency test failure wasn't updating FIPS status.
   Added new failure bit FIPS_FATAL_ECDSA_PWCT.
2. ECDSA KAT was only simulating error in verify, but not in sign.
   Split 'fips ecdsa' into 'fips ecver' and 'fips ecsign'.
3. Added a way to introduce self-integrity error by not updating FIPS
   module digest with 'FIPS_BREAK=1' during build.
4. Added reporting of FIPS module digest.

BUG=b:134594373
TEST=make CRYPTO_TEST=1;
in ccd test:
fips pwct; tpm_test.py should fail; fips should print error.
-
fips ecver; fips test reports ECDSA error
fips ecsign; fips test reports ECDSA error
-
FIPS module digest is printed
-
FIPS_BREAK=1 make CRYPTO_TEST=1 produce build with zero digest
reporint FIPS self-integrity error.
