If there is an expression receiver, we should process constructors only
of inner classes. Constructors of nested classes can be called only
on classifier

This is an addition to d4278250e6. Apparently we still need to produce
a new fake override for each inherited static member, because otherwise
we would try to determine the most specific return type, maximum
visibility, etc, all of which makes no sense for static members.

This diagnostic is reported in rare situations when
StubTypeForBuilderInference is kept as a parameter type
of for loop or lambda. Before this commit, we had in K1
"Could not load module <error module>" from IrLinker instead.

Usually we create synthetic property in java class if there is a property
from the base kotlin class and getter/setter with a corresponding name
in the declared scope or one of supertype scopes. But there is a case,
where the same supertype contains both property and getter:
```
// FILE: Base.kt
open class Base {
open val b = "O"
@JvmName("getBJava")
fun getB() : String = "K"
}
// FILE: Derived.java
public class Derived extends Base {}
```
In this case we shouldn't create synthetic property, because `getB()`
function is invisible for `Derived` class

The previous one was incorrect for K1 since parent of top-level function
is `IrClass`, not `IrPackageFragment`.
The change is non-functional, K1 still worked correctly, but had to do
some extra work when inlining `emptyArray` calls and produces less
performant bytecode.
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.

Previously we forced computation only for java and precompiled classes,
assuming, that binary class can not extend source class, but it's not
true in two cases:
1. Classpath substitution: class with same name declared in library and
the source (more rare case)
2. Metadata compilation: depends-on dependcies are passed in binary
format, so `expect class` may be a binary one and corresponding
`actual class` may be a source. So if some class in `common` module
extend this expect class, actual class will be substituted instead of it

This is needed because in case a static member is inherited via a Kotlin
class (class C in the newly added test), its origin becomes
FAKE_OVERRIDE which is technically not Java anymore. After this change,
we'll build fake overrides for static members from superclasses
regardless of whether they come from Java or Kotlin.
Also, move the previous logic of
isOverridableFunction/isOverridableProperty to the only call site at
IdSignatureFactory.

Before this commit, fir f/o builder was inconsistently
disabled in some places, while it should work only for lazy declarations
Attempt to use it for non-lazy declarations, without maintaining
invariant, that it would also be used for super classes
led to unpredictable results.
This commit introduces opt-in, and marks all related API to three types
* Propagate error to user
* Fine to use, as it's checked if ir f/o builder is enabled
* Fine to use, as it is definitely a lazy class.
Several cases of missing checks was fixed.

Java annotation interface fields are constant declarations that can
have any Java type and are not restricted in the same way that
method return types are for annotation interfaces.
#KT-65482 Fixed
We have two sources of truth in Fir2Ir - declaration storages,
which maps fir to ir symbols and symbolTable which maps
IdSignature to ir symbol.
The long-term goal is to have only one - declaration storages. This
commit goes to this goal by removing all symbolTable usages that are
straightforward to remove, i.e., all except:
1. classes as there is some code, that uses signature inside ClassSymbol
2. functions/properties as sometimes declaration storage fails to match
symbols correctly (i.e. for generated data class members)
3. type parameters, as we need to remove functions first.
As a side effect, it fixes some of the signature clash cases on valid
code, as we no longer rely on signature uniqueness, except cases
mentioned above.

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.

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`.

For destructing calls, the component type is used for the property type
in all cases. However, this can result in runtime and/or compilation
errors when the property is a var and changed, especially when the
component is a primitive but the property type is nullable. Instead,
only use the component type when the property is also a val.

... if the delegate happens to be a function call whose second
argument is a callable reference but not actually a provideDelegate
call.
The fix is to ensure that the call is _actually_ a desugared
provideDelegate call.
This fixes a CCE in a case where the delegate expression is a regular
function call and the second argument is a callable reference.
#KT-65165 Fixed
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.
