[jdk11u-dev] RFR: 8255410: Add ChaCha20 and Poly1305 support to SunPKCS11 provider [v2]

[Goetz Lindenmaier]

> I backport this for parity with 11.0.15-oracle.
> 
> I had to do a row of adaptions. There are some implementation
> differences, and many Java 17 usages that had to be changed.
> 
> In the original change in SunPKCS11.java, dA() is used 
> to give alias names of algorithms. It calls to 
> SecurityProviderConstants.getAliases().
> In SunPKCS11.java of jdk11 neither dA() nore getAliases()
> are available. It uses d() instead of da() and calls a 
> s() with a list of literal strings to give the alias names.
> SecurityProviderConstants.java is in java.base. The jdk11 
> version does not contain the list of aliases that can be 
> found in 17.
> 
> I looked up whether there are aliases listed for 
> "ChaCha20-Poly1305" in 17, but found none, so I added
> an empty call s() in SunPKCS11.java.
> 
> In P11AEADCipher.java I had to modify the syntax of 
> a switch statement.
> 
> In CK_SALSA20_CHACHA20_POLY1305_PARAMS.java
> I had to replace HexFormat.of().formatHex(...)
> which is a java.util class not in 11.
> 
> The tests use HexFormat heavily.
> I replaced it by HexToBytes() from TestKATForGCM and 
> by toHexString() from TestLeadingZeroesP11.java.
> To make these methods available I moved them to the 
> superclass PKCS11Test.java. 
> This way they can be used for potential later backports, too.
> I also had to adapt a switch statement using '->' to syntax
> know to 11.
