Fix various tests so that they can run on JDK 17

fix CanProxyToLocalhostTest: Proxy#toString changed slightly

fix JavaCompletionTask121FeaturesTest: add Record to test data

fix ConvertToRecordPatternTest and ConvertToNestedRecordPatternTest

 - enforce parsable source level for hint tests
 - update record patern syntax in tests

fix BroadCatchBlockTest: use stable/jdk-independent test files

 - jdk keeps removing throws declarations from methods, esp when they
   extend RuntimeException -> lets make our own test Klasses

 Stabilize JS Test testIssue215777 by Matthias

 - split golden files into two

NbTestCase method ordering is always using "natural" order

 - ClassLoader fields can not be accessed via reflection on JDK 12+
 - test method ordering options are not used anywhere atm
 - disable tests
