Review: https://jetbrains.team/p/kt/reviews/13244
Motivation:
```
// Module :lib
class Foo {
val member: Int = 2
}
// Module :app
// dependencies { implementation(project(":lib")) }
class Foo {
val member: Int = 2
}
```
Before the commit:
app_Foo.expectForActual is `null`
app_Foo.member.expectForActual = lib_foo.member
After the commit:
app_Foo.expectForActual is `null`
app_Foo.member.expectForActual is `null`
If I don't fix this problem then
`CommonizerHierarchicalIT.testCommonizeHierarchicallyMultiModule`
becomes red after I fix KT-59887 in the following commits
`app_Foo.member.expectForActual = lib_foo.member` happens because we
also need to match fake-overrides (KT-63550)
I didn't measure it, but theoretically, this commit should be a
performance improvement, becuase we reuse `expectForActual` cache
Additionally, The commit breaks some other tests (e.g.
compiler/testData/diagnostics/tests/multiplatform/headerClass/actualMissing.fir.kt).
The tests will become green again, once I fix KT-59887
Review: https://jetbrains.team/p/kt/reviews/13244
Motivation: Performance. When I fix KT-59887 in later commits, I will
make actual-to-expect resolve to work not only for actual declarations.
Considering that LLFirExpectActualMatcherLazyResolver worked even for
non-KMP projects that might be a potential performance regression
FirExpectActualMatcherProcessor in the compiler does the same thing (it
checks for MultiPlatformProjects before running the transformer)
Motivation: If I don't fix it then I will get a false positive
ACTUAL_MISSING in
DiagnosticCompilerTestFE10TestdataTestGenerated.Tests.Multiplatform.Enum.testSimpleEnum
after I fix KT-59887
The commit also fixes false positive diagnostic in
annotationArgTypeAliasWithArray.fir.kt test
Review: https://jetbrains.team/p/kt/reviews/13244
integrateConstraintToSystem and substitute functions are only used in
the FirBuilderInferenceSession
Move is needed to specialize implementation for builder inference and
avoid an introduction of accidental usages from other inference sessions
Use test compiler runner to compile JS libraries. Determine compiler
by the specified TARGET_PLATFORM. Add tests for dynamic type and
JS-specific .proto extensions.
Refactor the code for mock library compilation to make the switch
between platforms more straightforward.

Note on .kjsm library symbol providers.
It's not clear whether the provider is necessary for K2 IDE and whether
there will be libraries with .kjsm files that we are going to support.
Since there are no tests that can prove the correct work of the symbol
provider right now, it's better add them later if needed.
The existing tests cover only .knm files.

Separate class allows encapsulating comparison, equality, and structure of version parts.
It also makes more sense from API standpoint than plain `IntArray`.
To make sure that the correct version and flags are preserved during metadata transformation,
they are now stored inside KotlinClassMetadata.
Such change also makes it possible to make write() a member function of KotlinClassMetadata, further simplifying API.
Also, it allows tracking whether readStrict or readLenient was used to read metadata and prohibit writing accordingly.
Also provide transform() method as a shortcut for readStrict+write.
Related to: #KT-59441
In strict mode, an exception will be thrown when inconsistent metadata is encountered. In lenient mode, the reader will attempt to handle the inconsistent metadata by ignoring certain inconsistencies. This is a solution to a problem of reading metadata 'from the future' that is not allowed by default, but desired in certain cases. See updated ReadMe for details.
Also fix problem with Strict Semantics flag.
#KT-57922 Fixed
#KT-59441 Fixed
- Old backend support is not needed in `KtFe10CompilerFacility` anymore,
because it has been removed for the bytecode tool window, which was
the only user. The old backend is slated to be removed entirely.

We want to use it to generate builder classes for other
trees, just like we already do with elements (see `AbstractElement` and
`AbsractImplementation`).
This is an extended version of the fix in
57d912a5d4. We don't want to use any
plugins in code fragment compilation, but we still get them through
`project` because they are registered in IDEA. So we just fully
exclude `irPluginContext`.
#KT-63695 Fixed
This commit actually does two things:
- Adds Any scope to stub type
- Makes CheckDispatchReceiver treat stub types
as non-null for the unsafe call check to make such candidates viable
Related to KT-59369
We can omit `get` call to delegated property and inline
constant value directly. If we are not going to
do that, we can get a runtime exception because
all usages of const property will be inlined and the property
itself will be dropped.
