This fixes some type argument mismatch errors caused by a captured type
being approximated and then captured again.
Some places need to be adapted to work with captured types that
previously only worked with approximated types.
#KT-62959 Fixed
Now, we detect clashing signatures during serialization to KLIB and
report a compiler error if two or more declarations have the same
`IdSignature`
For example, for the following code:
```kotlin
@Deprecated("", level = DeprecationLevel.HIDDEN)
fun foo(): String = ""
fun foo(): Int = 0
```
the compiler will produce this diagnostic:
```
e: main.kt:1:1 Platform declaration clash: The following declarations
have the same KLIB signature (/foo|foo(){}[0]):
fun foo(): String defined in root package
fun foo(): Int defined in root package
e: main.kt:4:1 Platform declaration clash: The following declarations
have the same KLIB signature (/foo|foo(){}[0]):
fun foo(): String defined in root package
fun foo(): Int defined in root package
```
Note that we report this diagnostic during serialization and not earlier
(e.g., in fir2ir) for more robustness, so ensure that we check
exactly the signatures that will be written to a KLIB.
If we later introduce some annotation for customizing a declaration's
signature (e.g., for preserving binary compatibility), this
diagnostic will continue to work as expected.

It's expected to partially mimic the behavior of what
previously was called builder inference, but with more clear contracts
(documentation is in progress, though)
See a lot of fixed issues in the later commits with test data,
especially [red-to-green]
^KT-59791 In Progress
Previously, because we didn't handle flexible types properly in
prepareCapturedType, projections inside flexible types would only be
captured during subtyping with captureStatus=FOR_SUBTYPING
which would lead to the constraint type being wrongly approximated
(see ConstraintInjector.TypeCheckerStateForConstraintInjector
.addNewIncorporatedConstraint).
Fixing the capturing produced two kinds of false positive diagnostics:
1. In ConstraintInjector.TypeCheckerStateForConstraintInjector
.addNewIncorporatedConstraint we would get two instances of cone types
that are structurally equal and containing the same captured type.
However, because we only skipped subtyping if the types were
referentially equal, we would get a contradiction here.
The fix was to use structural equality instead, which should be okay
as the captured type instances are the same.
2. Reified type variables were inferred to captured types because
flexible arrays with captured upper bounds
(Array<Foo>..Array<Captured(out Foo)>?) were not properly approximated.
#KT-62609 Fixed
This fixes the difference at least in the IR text test
testFakeOverridesForJavaNonStaticMembers. There's no fake override
created anymore for `packagePrivateMethod` in Test2.
#KT-61366 Fixed
- AnnotationDescriptor#argumentValue is not frontend-specific
- AnnotationDescriptor#getAnnotationStringValue is not Native-specific
We are going to need these functions in the IR code, so it makes
sense to factor them out to the core module.
^KT-61039 Fixed
KT-59739 is now open for K1 (but fixed in K2)
Review: https://jetbrains.team/p/kt/reviews/11867/timeline
This partially reverts commit 4f3ecedbca.
Only K1 part is reverted.
Motivation for revert: KT-59739 cannot be properly fixed in K1 because
of the bug it causes - KT-61039
We just accepted that we will have one more "green in K1 -> red in K2"
case
To avoid case with NPE due to race-condition on publishing
non-fully initialized object in ctor via
`TypeRefinementSupport.Enabled(this)`

The issue is that during binding fake overrides, the compiler doesn't
differ setters from its properties, so the compiler uses the same
visibility for setter and entire property.
Changing logic at the binding stage can cause some unpredictable consequences so
the fix is to do this differentiation right at the reporting stage

See the comments in the code, but mostly the motivation is that once
it was decided to stick with such a legacy thing as raw types,
we are ok with some corner-cases hacks for them
(if there are not too many of them) and they don't break anything
when there are no raw types in the code.
^KT-56616 Fixed
Not fully initialized DeclarationDescriptor could leak to bindingTrace.
It is hard to detect the outcome of that kind of leakage due to
possibility to have not fully initialized instances if PCE happens in
the middle of publication and instance full initialization.

FunctionalTypeKind can be used in FE 1.0 too, so there is no need to
keep both classes. Also, removal of FunctionClassKind simplifies work
with FunctionalTypeKind in common code, like Analysis Api
Resolver could be GCed if there is no any valid hard reference to it.
Some impl of PackageFragmentProvider (like DelegatingPackageFragmentProvider)
keep hard ref to resolver.
For the sake of investigation it is worth to know what kind of PFP is there.
