This changes the logic so that Foo<T> is reported no matter if T is
reified or not. Even for Array<reified T> to align K2 with K1 logic.
#KT-55903 Fixed
This is a partial revert of 949a39b80f. In the end it turned out not
necessary to prohibit this case (and perform a breaking change), because
JVM backend was fixed to generate it correctly in d73d3c46e2.

Since we forbid overriding `equals` for
value classes, and value classes may only
implement interfaces, we know everything
about their `equals`, hence we can
guarantee if it always returns `false`
for different value classes.

Review: https://jetbrains.team/p/kt/reviews/9677
This commit fixes an inconsistency between
FirUnsupportedSyntheticCallableReferenceChecker and
UnsupportedSyntheticCallableReferenceChecker
In K1 such properties were not considered synthetic and are called
JavaPropertyDescriptor. That's why we need to do an additional check in
K2 checker, while in K1 we didn't need to do it
Also see the previous commit for more related tests that already was
green without this fix but are related to KT-58061 problem

Meta issue: KT-8575
Review: https://jetbrains.team/p/kt/reviews/9595
UnsupportedSyntheticCallableReferenceChecker only existed for K1,
because we wanted to release the feature for 1.9 and the feature should
have been working for K2 unconditionally. But since, we're postponing
the release until 2.1, we also need to port the checker from K1 to K2
Add a special annotation @JsExternalTypeArgument for
marking function parameters. The marked parameter
accepts an argument with an external type only.

This fixes a scenario when INVISIBLE_REFERENCE is suppressed, but we
resolved to the wrong overload because when none of the candidates were
applicable, more or less the first one was chosen.
Because we call `fullyProcessCandidate` on the candidates, their
applicability can change which can lead to a situation where the
applicability of a ConeAmbiguityError is different to all its
candidates. The changes in coneDiagnosticToFirDiagnostic.kt account for
that, otherwise code like candidates.first { it.applicability ==
CandidateApplicability.UNSAFE_CALL } can throw NoSuchElementException.
#KT-57776 Fixed
The change in `FirDiagnosticsHandler` ensures
`DEBUG_INFO_DYNAMIC` is still reported in
`FirPsiJsOldFrontendDiagnosticsTestGenerated.testConventions`.
Support `SPREAD_OPERATOR_IN_DYNAMIC_CALL` and
`WRONG_OPERATION_WITH_DYNAMIC`
Add a special annotation @JsExternalInheritorsOnly for marking
external interfaces and classes. The marked interface or class
can’t be a parent for non external interfaces, classes or objects.

The compiler should only report diagnostics for
comparisons over builtins and identity-less types,
other incompatibilities should be reported
via inspections.
It's ok that in `equalityChecksOnIntegerTypes`
instead of `EQUALITY_NOT_APPLICABLE_WARNING` we get
`EQUALITY_NOT_APPLICABLE`, because
`ProperEqualityChecksInBuilderInferenceCalls`
is already active by default.
This change also replaces the notion of a representative superclass
with the least upper bound.
This makes complex types like
intersection/flexible transparent to
RULES1-based compatibility checks.
One way to look at it is to think
that this is an automatic way of handling
type parameters: automatic picking of
"interesting" bounds, and checking them against one another.
Note that `TypeIntersector.intersectTypes`
for `Int` and `T` where `T` is a type parameter
may return both `{Int & T}` or `null`
depending on `T`-s bounds. At the same time,
for type parameters `T` and `K` it will
always return `{T & K}`.
`ConeTypeIntersector.intersectTypes`, on the
other hand, will always return `{Int & T}`
irrespectively of the bounds. Meaning, the two
intersectors differ in corner cases.
`lowerBoundIfFlexible` call in `isLiterallyTypeParameter` is backed by
the `equalityOfFlexibleTypeParameters` test.

The only case when behavior is change is described at
computeNonTrivialTypeArgumentForScopeSubstitutor
The idea is to avoid depending on the presence of @UnsafeVariance
and instead approximate captured types in covariant argument positions
before building substitution scopes
It's correct because for Captured(*) <: Supertype,
Out<Captured(*)> <: Out<Supertype> and when we've got @UnsafeVariance
value parameters at Out, it's ok to allow passing Supertype there.
