8256660: Disable DTLS 1.0

[GoeLin]

I backport this for parity with 11.0.24-oracle.

Trivial resolve in java.security

Update:
Two test were failing with this change: javax/net/ssl/DTLS/InvalidRecords.java and javax/net/ssl/DTLS/NoMacInitialClientHello.java. Thanks to Sean Mullan who pointed me to the fix, see also

⚠️ @GoeLin This change is now ready for you to apply for maintainer approval. This can be done directly in each associated issue or by using the /approval command.

[MBaesken]

Seems there are quite a lot of tests at test/jdk where 'jdk.tls.disabledAlgorithms' is set to a small number of disabled algorithms . Those settings were probably fine a long time ago, but for some of them it might make sense to review, if it would make sense to add more disabled algs that were add in the meantime .
But this is of course out of scope of this backport .
