[jdk21u-dev] RFR: 8344137: Update XML Security for Java to 3.0.5

[Goetz Lindenmaier]

I backport this for parity with 21.0.8-oracle.

Clean backport except for GenerationTests.java.
That differs because the backport of this update always
omits the new signature method Strings so that the standard
must not be touched, see also the backport CSR.
The test was adapted to this in the past in 21.

We need to adapt this change, too.

We can just skip the chunk that does not apply
in GenerationTests.
It increments the number of methods, but as this
is not changed in 21 we don't need this.

In an extra commit I remove the new method strings and 
adapt the test to it.
