Review: https://jetbrains.team/p/kt/reviews/10385
`isData` returns `true` for `data object`s even if kotlin-reflect
version is old (1.2.0), so it looks like we got correct `KClass.isData`
behaviour for "free". That's why this behaviour was never covered with
tests.
This commit updates the documentation and covers the behaviour described
in the KDoc with tests.
Cases when default argument inhertied from super class are allowed.
Some tests for default arguments already exist and can be found in
`testData/diagnostics/tests/multiplatform/defaultArguments`, for example
`annotationsViaActualTypeAlias.kt`.

This doesn't reduce the quality of tests, because the flags are still
printed for declarations themselves. We only omit them in references.
However, this makes the tests more compatible with non-JVM backends
(see KT-58605), because flags of referenced stdlib declarations may
differ among target platforms.
When an annotation constructor value parameter is annotated with the
very same annotation, FIR2IR went in an infinite loop when trying
to generate it.
To fix this, the constructor is added to the Fir2IrDeclarationStorage
cache before generating the value parameters.
To accommodate for the missing parameters, the value arguments count
is determined using the FIR.
The feature was previously enabled unconditionally in K2 which
triggered a bug when an enum has an entry with the same name as itself.

Earlier, it wasn't really important but after the previous commit
when JvmMappedScope semantics has been changed, we erroneously
started loading `toCharArray` as a member to String because
its jvmDescriptor was computed to "toCharArray()Lkotlin/CharArray",
while hardcoded information that prevents it from loading expect
"toCharArray()[C" there.

Previously, the semantic was more-or-less correct for most of the cases
but some corner one, like `sort` in MutableList didn't work properly.
Namely, `sort` should be marked there in a way to forbid to call it
everywhere beside super-calls.
Also, overriding it should be allowed.
Mostly, the logic was re-written to K2 model from K1-related
JvmBuiltInsCustomizer.

> Condition 'isSuspendFunctionType' is always false when reached
The change in the native tests is needed, because K2
doesn't support disabling old language features

When BI/incomplete call is present in return argument, it will be
added to the main call-tree, leading to requirement violation in
`ConstraintSystemCompleter.getOrderedAllTypeVariables`
as after `FirBuilderInferenceSession.inferPostponedVariables` it will
be completed, and its type variables couldn't be found anymore
In K1, we actually do the same, but we are able to find type variables
of such calls due to architecture difference:
In K2, `getOrderedAllTypeVariables` uses FIR as the main source to
lookup
In K1, `getOrderedAllTypeVariables` uses resolution atom tree, where
candidate/CS of the call is still available after
`inferPostponedVariables`
In fact, all incomplete calls were analyzed in FULL mode according to
the contract of `FirBuilderInferenceSession.addPartiallyResolvedCall`.
Thus, it means we normally shouldn't add them to the main call-tree, but
accidentally do it as incomplete calls contain non-completed candidate
This particular commit addresses the problem partially, only
in cases when the expected return type for the lambda is Unit and when
the incomplete call is located in the last expression of the lambda
In such cases, we can skip the call from the last expression completely,
since all potential calls there were analyzed in FULL mode,
and couldn't introduce any useful info to the CS of the main call-tree

This commit adds missing pieces for the puzzle:
Annotation instantiation feature uses IrProperty's initializer to instantiate
properties from other modules that have default values which weren't
specified on call site.
To support this feature properly, Fir2IrVisitor should fill LazyIrProperty's
backing field initializer with information from Fir.
To get this information into Fir, FirMemberDeserializer should be able to read
it from KotlinJvmBinaryClass with AnnotationLoaderVisitorImpl. (klibs are unsupported for now)
There's a catch with enum entries references: we can't access session.SymbolProvider to resolve it
because we're still at the deserialization stage, and it can cause StackOverflow if enum is nested in the
same class (see RequiresOptIn.Level). To mitigate this, a new FirEnumEntryDeserializedAccessExpression is produced
instead; it is later replaced with the correct reference in the Fir2IrVisitor.
^KT-58137 Fixed
Also add test to loadJava folder with annotations default values that
verifies metadata loading
Java declarations do not have a file parent, their outer element is
IrExternalPackageFragment.
The test did not fail in K1 only by accident, because there's an extra
IrTypeOperatorCall on the property reference's dispatch receiver, which
automatically makes it non-inlinable. In K2, it's IrGetField, so we were
trying to compute if its dispatch receiver is inlinable and for that we
tried to get its fileParent, which resulted in exception if it comes
from Java.
Also refactor PropertyReferenceDelegationTransformer.canInline a bit.

Previously, when a candidate was found with an applicability that is
better than the current best applicability, all previous candidates were
thrown away. Now we keep them, unless the new applicability is
successful. If no successful candidates are found, we fully resolve all
the unsuccessful ones and select the ones with the least bad
applicability. This improves diagnostics for unresolved calls.
