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

[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.
