RFR: 8312428: PKCS11 tests fail with NSS 3.91

[Valerie Peng]

Starting NSS v3.91, SHA-3 support is added for MessageDigest but not for PSS Signature. This breaks existing test assumptions made by PSS regression tests. In addition, the NSS SHA-3 message digests do not support cloning which causes the failure of TestCloning.java.

This PR adds a PSSUtil.java class which provides utility method for detecting/guessing whether a digest algorithm is valid for PSS signature or not.

The changes are verified with NSS v3.46, v3.57 and v3.91 (on local Linux machine).

Thanks in advance for review~
