Basically, the test checks that adding Enum.entries feature doesn't
break the existing code where it clashes with the user-defined "entries"
declaration; it's better to have a black-box test to be sure
that the compiler doesn't invoke something different at runtime
The test covers KT-53153 and KT-56587

Most of these tests check the specific structure of lambdas when they
are generated as classes, and they start to fail once invokedynamic
lambdas are enabled by default.
Use -Xlambdas=class in tests which were checking specific things related
to how anonymous classes for lambdas work (such as receiver mangling,
function arity etc.)
since we generate the default getter in this case in
Fir2IrDeclarationStorage.createIrProperty, so the serialized metadata
should follow the same behavior.

The tests are removed because JvmDefault is going to be deprecated with
error in KT-54746 and removed later in KT-57696.
Many of the removed tests already had existing counterparts with the new
modes `all` and `all-compatibility`. In this change, I've added such
tests where they were missing, and removed tests which were testing
behavior specific to the JvmDefault annotation, such as some
diagnostics.

The changes to the irText test data result in the fact that we
now unconditionally unwrap substitution overrides of delegation targets
whereas before we built an unsubstituted scope of the type we delegate
to. If we delegate to a class A : B<C>, the unsubstituted scope of
A can still contain substitution overrides for inherited generic methods
from B<T> that we didn't unwrap before but do unwrap now.

Current qualified access resolving algo rely (likely incorrectly,
see #KT-58037) on a providers' "knowledge" about parent packages.
This commit adds this "knowledge" to k-lib based provider.
#KT-57353 fixed
This fixes a scenario when INVISIBLE_REFERENCE is suppressed, but we
resolved to the wrong overload because when none of the candidates were
applicable, more or less the first one was chosen.
Because we call `fullyProcessCandidate` on the candidates, their
applicability can change which can lead to a situation where the
applicability of a ConeAmbiguityError is different to all its
candidates. The changes in coneDiagnosticToFirDiagnostic.kt account for
that, otherwise code like candidates.first { it.applicability ==
CandidateApplicability.UNSAFE_CALL } can throw NoSuchElementException.

tl;dr the current design of klibs does not allow to properly deserialize
the list of sealed subclasses in a sound way. It is possible that
a subclass of a sealed class is declared in a different file, AND is
private in that file.
A more detailed explanation:
Right now we don't serialize file signatures at all.
However, a private declaration's signature must necessarily include
the file signature.
How do we serialize a private declaration's signature into a klib
and deserialize it later?
**Serialization** is simple: we just serialize the file signature as
an empty protobuf message.
When we are **deserializing** a private declaration, we look at the file
that is being deserialized right now, and construct the file signature
based on that.
This logic, however, doesn't always work. An example is KT-54028.
Basically, if we have a sealed interface with a private implementor
declared in a different file, this breaks:
1. We are deserializing the sealed interface. The deserializer knows
that we are now in the file in which the sealed interface is declared.
2. As part of deserializing the interface, we deserialize its sealed
subclasses.
3. Naturally, we come to deserializing the private implementor that is
declared in another file, but the deserializer still thinks that we are
in the file in which the interface is declared. A wrong signature is
created, which leads to linkage failure.
We *could* fix this by properly serializing the file signature,
i.e. instead of an empty protobuf message we could write the file path
and its package to the klib. However, there a problems with this
approach:
- The current design of signatures allows a situation where two
different files can have the same relative path
(for example, with the help of the `-Xklib-relative-path-base` compiler
flag) *and* the same package, which would introduce ambiguity during
linkage.
- Most importantly, this appoach won't work well with incremental
compilation of klibs. Currently we rely on the assumption that all
cross-file references are handled with public signatures, and private
signatures are only used inside a single file. This allows to move
declarations across files without recompiling it's use sites.
It has been decided to apply the following hacky solution: we just don't
deserialize the list of sealed subclasses from klibs.
The list of sealed subclasses is not used in lowerings, so it should be
safe.

Overriding equals, hashCode, toString and any other member that is not
expect does not require satisfying the rules of expect-actual matching.
