It's effectively a breaking change (^KT-62558)
K2 assigns flexible type to all static fields (from Java) and, for example,
`String? becomes String unlike K1. It affects IR signature generating.
That's why signature dump is disabled for some tests.

Before this commit, we added Enum.entries only in case when
LanguageFeature.EnumEntries was ON (with an exception in K1/Java case).
In this commit we add Enum.entries unconditionally, and in case
the language feature is OFF we filter them out during tower resolve.
1. Inner class constructor should have its outer class as a dispatch
receiver, since it is necessary for the call. Before it was null
2. Substituted inner class constructor should have its original dispatch
receiver type with the proper substitution. Before it was set to the
class itself (since the class was usually passed as a new dispatch
receiver)
Also, modify FIR renderer, so it properly renders the dispatch receiver
of the constructors
Because those test are single Java files, many of them use a top-level
class as a container for multiple classes to be tested. Such tests do
almost nothing if those nested classes aren't handled.
- Add utilities to add new attribute to ConeAttributes
- Get rid of FlexibleNullability attribute (it can be easily inferred
for any flexible type at any moment)
- Fix determining of EnhancedNullability attribute
This makes sense because this mode is the default in the production
compiler. Forgetting to enable it where necessary led to different
bizarre test failures, see for example changes around 3fee84b966 and
KT-34826
Really, this commit implements early J2K mapping for all Java types.
It's questionable and probably wrong at least for super-types,
because, for example, we cannot resolve spliterator() in classes
derived from java.lang.Iterable
In case Java enum has an abstract member, it has the ACC_ABSTRACT flag
set in the bytecode. However, we should still load it with final
modality to be consistent with Kotlin enums which are always considered
final

Main test data (testName.txt) a not totally valid cause of IDEA-205039.
Javac test data (testName.javac.txt) a not valid
cause of type annotations support absence.
Runtime tests are disabled cause reflection support absence.
