Java type enhancement is performed by a special scope kind
Java FIR dump was added for multiplatform tests to look at enhancements
Overrides, J2K mapping, special cases does not work yet

It becomes necessary after extracting supertypes resolution into a
separate phase.
But also it looks reasonable because direct expansion actually depends
on the module we are looking from.
The `*Api`, `*Implementation`, `*CompileOnly`, and `*RuntimeOnly`
configurations of a `KotlinSourceSet` must not be resolved directly, as
they lack attributes needed to choose a Kotlin MPP variant, and they
must not be candidates in variant-aware resolution of a project
dependency either.
With Gradle 5.3, these configurations failed to resolve anyway, as they
had no proper `org.gradle.usage` attribute, and the disambiguation
rules of the 'java-base' plugin conflicted with the Kotlin rules.
In Gradle 5.3, there was a change to the internal logic of publishing
`SoftwareComponent`s with the 'maven-publish' plugin, and,
simultaneously, a new public API was introduced for user-defined
software components, see https://github.com/gradle/gradle/pull/8399
Earlier, the 'maven-publish' plugin used the Gradle `Usage` attribute
values to arrange the dependencies of a software component's
`UsageContext`s into the Maven scopes. Now that mechanism doesn't work
and a `SoftwareComponent` must provide an explicit mapping of the
variants to POMs by using the `SoftwareComponentFactory.adhoc` API.
However, the new API lacks some features we need to properly publish an
MPP, such as adding a component to another one as a variant, so we still
create old-style software components under the hood and
then wrap them into the new API (and then wrap the adhoc components once
again).
We also continue to use the old-style components for Kotlin-specific
logic like finding a target in another project that a dependency
resolved to, as the components produced by the new API lack crucial
information that is used in the logic, like references to
`KotlinCompilation`s.
Issue #KT-30379 Fixed
The support on our side involves:
* using the new value for Maven publishing, as the 'maven-publish'
plugin now expects 'java-api-jars' for dependency scopes ordering where
it used to expect 'java-api'
* accepting the new value in KotlinUsages compatibility and
disambiguation rules
Only Ctrl + Click is affected as find usages from Alt + F7 is a different
action (`GotoDeclarationAction` is `DumbAware`, but `ShowUsagesAction` is not).
