RFR: 8255410: Add ChaCha20 and Poly1305 support to SunPKCS11 provider [v3]

[Valerie Peng]

> Could someone (perhaps Jamil?) please help review this change? This enhances SunPKCS11 provider with ChaCha20-Poly1305 cipher and ChaCha20 key generation support. Majority of the regression tests are adapted from the existing ones for SunJCE provider's ChaCha20-Poly1305 cipher impl. When testing against NSS v3.57, it does not have support for ChaCha20 cipher, thus I did not add support for ChaCha20 cipher and the corresponding parameter.

Valerie Peng has updated the pull request incrementally with one additional commit since the last revision:

  Fixed an tagLen issue, no key+iv reuse check for decryption, and add regression test for ChaCha20 SKF.
