Improve handling of Java annotation parameters

[IgnatBeresnev]

This PR fixes 3 issues that all came from the same place. See the tests, there's one for each issue.

Fixes #2509
Fixes #2551
Fixes #2350

I've also tried to make it so that it doesn't lead to build failures in case some other corner case is not covered, although it might come with some signature bugs for such situations.

Note

Source code

@SimpleAnnotation(clazz = String[].class)

Will be rendered as

@SimpleAnnotation(clazz = String::class)

This is probably incorrect and it might be better to generate Array::class instead, but I've had a look at how we handle such cases for Kotlin sources and it's actually generating String::class, so I think it's better to have the same behaviour for both Kotlin and Java. This is to be discussed and fixed separately as it would require introducing changes to the annotations model.
