[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.

The backport was almost clean, except for two trivial resolves due to differences in whitespace in the context.

The change comes with a CSR, which is already approved for 17.
But the CSR requires changes wrt. to the original change. 
In 17, no EDDSA support is added.

The PR comes with two commits:
1. the almost clean backport
2. removing the eddsa support.

Tests pass, SAP nightly testing passed.
