RFR: 8302233: HSS/LMS: keytool and jarsigner changes

[Weijun Wang]

Code changes for HSS/LMS that's related to keytool and jarsigner:

1. No need to add `-sigalg` for both tools when HSS/LMS key is involved, it can only be `HSS/LMS`.
2. The `digestAlgorithm` field in a PKCS7 `SignerInfo`. It must be the same as the hash algorithm used by the HSS/LMS key. This needs to be enforced both at signing and verification.
3. HSS/LMS reuses `.DSA` as the signature block file extension inside a signed JAR file
