[groovy] tests: split RepositoryProjectDescriptor into TestLibrary and LibraryLightProjectDescriptor

Inspection does not register `CompatibilityVisitor` problems for its opened file language because in such a case
`UnsupportedFeatures` will annotate them.
Also `registerOnFirstMatchingVersion` methods were removed because
they could lead to duplication even if languages to register were different.

Although `TestPlan` exposes an `add(TestIdentifier)` method, it was only
ever intended for internal use by JUnit's `DefaultLauncher` which
already adds dynamic test identifiers to the `TestPlan`. The JUnit team
is going to make the `add()` throw an exception on modifications from
listeners. Thus, this commit removes the unnecessary call.
