Remove FirEmptyOverridesBackwardCompatibilityHelper since it's not used anymore
Remove overridesMemberWithPlatformDependent.kt test file since it becomes redundant
This is needed because in order to figure out which declarations are
visible from anonymous objects in terms of overridability (see
`FirVisibilityChecker.isVisibleForOverriding`), we need to get the
package name of that anonymous object, because there's package-private
visibility on JVM.

See the comment at updateSubstitutedMemberIfReceiverContainsTypeVariable
It became necessary after delegate inference is rewritten, since before
that happened, stub types were being left there and FIR2IR handled
them accidentally properly because stub types are equal to anything.
But that wasn't really correct even there because stub types are not
intended to leak out of the FIR
^KT-61060
The main idea is getting rid of stub types and using just type variables
See more detailed description at docs/fir/delegated_property_inference.md
The problem with stub types is that they need really special treatment
in many places, and on the other hand, there are no clear contracts on
how they should work (that regularly leads to bugs like KT-59529)

Optimization in 2439c22ff6 introduced an array `absentArguments` with
default values of all parameter types, which is copied in `callBy`
instead of being recomputed each time. Unfortunately, its size was
computed incorrectly: `maskSize` should only take into account
value parameters (see the `parameter.kind == KParameter.Kind.VALUE`
check in `callBy`).
This led to an issue where if the function had 32 * N value parameters
and 1 receiver parameter, `maskSize` was greater by 1 than expected,
which caused an exception due to mismatching argument array sizes.

The only case when erasure matters in a context of materialization of
`PromisedValue` is when the type is a type parameter which upper bound
is an inline class. Since `PromisedValue::materializeAt` is a hot spot
and `eraseTypeParameters` is an expensive operation, we should not do
type erasure in other cases.
If some function is not fake-override, then its type should be just
default type of containing class
For fake overrides the default type calculated in the following way:
1. Find first overridden function, which is not fake override
2. Take its containing class
3. Find supertype of current containing class with type constructor of
class from step 2

Currently, there is only attribute `ExpectForActualAttributeKey`
where mapping is stored only for source declarations with `actual`
modifier. But we need mapping of all class members, including classes
which were actualized via `actual typealias` or fake override members.
This data will be needed for the annotation checker in subsequent
commits.

Disabling the language feature is supported,
otherwise there are too many tests that
would need to be updated to account for
K2's inability to do it.
The `ifConstVal.kt` test is deleted,
because now it must also be ignored in K2,
and since it is ignored for both the
frontends, and the ignored backends
include all the target backends, this test
is basically unused.
Note that now both the frontends report
`CONST_VAL_WITH_NON_CONST_INITIALIZER`.
for `condition`.

This fixes a KMP issue where IrActualizer would add duplicate
fake overrides because the parent class would have both the getter
and the synthetic property in its list of declarations.
Now, the synthetic property fake overrides are still generated and
cached in the Fir2IrDeclarationStorage, but not added to the class.
#KT-60854 Fixed
This change covers the case where some f/o was generated in common module
and it is referenced in platform code. But signature of this f/o may be
different in different modules because of e.g. actualization of value
parameters with actual typealias
