Fix some unresolved supertypes. This is necessary to be able to enable
IR fake override builder by default (KT-61514), because it traverses all
supertypes and asserts that they're classes, so that it can build fake
overrides for declarations from there. Without this change, for example
`IrFakeOverrideBuilder.buildFakeOverridesForClass` would crash.
A class can inherit two declarations that are compatible from the
overridability standpoint and are therefore combined to a non-trivial
intersection.
At the same time, the class can declare a member declaration that
only overrides one of the intersection's members.
In this case, we break up the intersection and only add the overridden
parts to the declared member's direct overridden list.
If the class doesn't override the intersection, it exists as
intersection override, like before.

This helps to have a primitive array instead of an array of primitives
as the type of vararg value parameter. Also, this prevents
ABI-incompatibility with the libraries (KLIBs) compiled with K1.

Copying tree part happens in two stages.
1. Collect all symbols to copy and create new version of them
2. Do copy tree, replacing collected symbols
For f/o builder 1-st stage traversed more nodes, than seconds.
This led to unbound symbols in tree.

Q: How resolved modality of an accessor affects expect/actual matching
algorithm of properties?
A: It's not expect/actual matching of properties, but expect/actual
matching of properties setter. Declarations (setters in our case) in
actual are allowed to have wider visibility but only if the
appropriate expect is `final`. Before this commit, all property
accessors were always `final` by mistake. After this commit, they
have the modality derived from their containingProperty.
Related problem: PositionStrategy for ACTUAL_WITHOUT_EXPECT can be
improved KT-65720
The fix in `resolveModality` is similar to how `resolveVisibility` works

This commit is intended to deal with inconsistency in K1/K2
star projection handling.
K1 star projection includes a 'type' property.
This type from a star projection can be used for relevant
functions / properties return types,
and already includes some approximation for recursive generics.
In contrast, K2 star projection is an object,
and return types of relevant functions / properties are
represented as captured types.
To prevent recursion in them in recursive generic case,
this commit includes additional replacement of their type arguments.
See more details in added comments.
#KT-65057 Fixed
Otherwise it leads to the following problem in the newly added test.
Suppose that we have a fake override `remove(Int)` inherited from
LinkedList _without_ EnhancedNullability on its parameter type. By
normal Kotlin rules, this method should override the method from
KotlinInterface. However, on JVM we have another overridability check in
IrJavaIncompatibilityRulesOverridabilityCondition which ensures that
"JVM primitivity" of parameter types is the same for the base and the
overridden method.
So the fake override `remove(Int)` from LinkedList is determined to be
override-incompatible with `remove(Int)` from KotlinInterface. But when
we try to create symbols for all fake overrides in the class, we get a
clash because there are two fake overrides with exactly the same
IdSignature, neither of which overrides the other.
If we keep the EnhancedNullability annotation on the parameter, it
starts working because the logic of computing signature in
JvmIrMangler.JvmIrManglerComputer.mangleTypePlatformSpecific adds an
"{EnhancedNullability}" mark to the IdSignature of a fake override from
LinkedList.
#KT-65499 Fixed
Unfortunately, it's not enough to know direct overriddens
to correctly build fake overrides. This mean, that we need to know
whole overridden tree during the process of building.
It happens automatically for normal classes, but not for lazy classes,
as their overriddens are built separatly.
This commit enforces correct overrddens for lazy classes in hierarhies
at the point, where they should be normally computed.

There's an implicit contract in PCLA that the statement-level call
should be postponed iff it has something to be postponed inside.
And that contract didn't work well for string interpolation containing
some postponed calls.
Thus, we haven't run a completion results writing for them properly,
thus leaving type parameters (K from synthetic call) for expression
types instead of an inferred substituted type.
In this commit, the contract was reversed to explicitly enumerate
the cases when it's safe to resolve the candidate outside PCLA session.
See the comments at `mightBeAnalyzedAndCompletedIndependently`.

When a type annotated with @PurelyImplements (explicitly or implicitly)
inherited some methods from a java supertype and the purely implemented
Kotlin supertype, it was inconsistent which of the signatures the
intersection override would have (with or without flexible types).
This commit adds support for the enhancement of intersection overrides.
If one of the overridden methods has non-flexible types, the enhanced
method will have non-flexible types.
This fixes some false negative nullability type mismatches.

This fixes a bunch of missing overridden symbols in IR.
This is also required for fixing KT-59921 in the following commit
where we need to keep all overridden symbols of intersection overrides
so that we can enhance them properly.

We drop Kotlin function 'remove' or 'getOrDefault' from JvmMappedScope,
if it has platform-dependent annotation, and the bound Java class scope
does not contain a function with the same signature.

NB: in order to produce correct IR origins, the source element kinds for
some FIR elements has been changed. As a side effect, mapping PSI to FIR
slightly changed: namely, for `a[b]++`, `a[b]` used to be mapped on
`set` call or callable reference, but now it is mapped on `get` call.

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
This origin was set somewhat arbitrarily.
It actually only makes sense for `IrCall`s to property getters.
There were no places in lowerings that checked `IrGetField` expressions
for this origin value.

...instead of those computed from a frontend representation
(`symbol.signature`).
This is more robust; besides, we are going to turn off building
signatures from FIR, so `symbol.signature` is going to return null soon.
While not beeing final solution, this is closer to what
we want to have in the end. Enabling on non-JVM targets
would help better testing.
Enabling in JVM is now not possible yet, as some of the bugs are
not fixed yet (check KT-61360 for details)

We don't have true flexible types in the IR, but we approximate it with
internal type annotations, such as FlexibleNullability,
FlexibleMutability, RawType. These annotations are then handled
specially in JvmIrTypeSystemContext, which can construct a fake flexible
type so that type checker on IR types would behave exactly as on
frontend types.
As shown in KT-63441, one instance of flexible types where flexibility
was lost during conversion to IR is Java array/vararg types. It's
necessary to support it so that IR fake overrides could be constructed
correctly, because IR fake override checker requires parameter types to
be equal. So this change introduces another internal type annotation,
FlexibleArrayElementVariance, which is only applicable to types with
classifier kotlin/Array, and which signifies that the annotated type
`Array<X>` should rather be seen as `Array<X>..Array<out X>`.

This commit gets rid of the redundant typeApproximatorConfiguration
in Fir2IrTypeConverter and uses the type approximator for captured
types instead of the manual approximation used before.
This fixes the nullability of approximated captured types, which fixes
a runtime error in WASM.
This also brings K2 IR closer to K1 IR in one test.
