[jdk17u-dev] RFR: 8305972: Update XML Security for Java to 3.0.2

[Goetz Lindenmaier]

I backport this for parity with 17.0.11-oracle.

This is a  minimal version that only removes the strings from the interface, as well as the comment. Removing these is explicitly stated in the CSR.

The change keeps the EdDSA implementation. As I understand, 17 supports EdDSA in general, it was just not included for XML when 17 was released.
