The JsAllowValueClassesInExternals feature is enabled explicitly,
because otherwise it's enabled
implicitly depending on the backend. See:
org/jetbrains/kotlin/test/builders/LanguageVersionSettingsBuilder.kt:90
A property may have a fake source return kind, while its accessor
has a real source kind. In this case we can't "just copy"
the property return type down to the accessor.
This should solve the problem with deadlocks/performance in the K2 IDE
This is a temporary solution until the ^KT-55387 is properly fixed

No clue where to put the test for that since diagnostic tests, even
multi-module ones, never touch the metadata serializer. So the test is
a bytecode text one pretending to be about nullability annotations even
though it also affects what resolution in another module will do.
Note that there is a questionable behavior that will be fixed later.
Right now it's not fully clear because for the same situation in Kotlin, the compiler reports warnings at declaration-site and it's not possible to do so for Java

- If too few or too many type arguments were provided, they were all
thrown away in `TypeArgumentMapping`,
`FirCallCompletionResultsWriterTransformer`, and `KtFirCallResolver`.
The fix handles type arguments of the wrong arity more gracefully.
- Note for `TypeArgumentMapping`: Excess type arguments are not needed
for candidate resolution. Excess type arguments are still resolved
due to the handling in `FirCallCompletionResultsWriterTransformer`.
- Post-processing in `AllCandidatesResolver`: When all candidates are
resolved in `AllCandidatesResolver.getAllCandidates`, the function
builds a FIR file. During that resolution, the
`generic<String, String>` call (in example
`functionCallWithTooFewTypeArguments.kt`) is correctly marked as
inapplicable, but the missing type argument is inferred as an error
type. `firFile` then contains a function call
`generic<String, String, ERROR>` instead of `generic<String, String>`.
This call is still marked as inapplicable. Despite that, the
*subsequent* resolution by
`bodyResolveComponents.callResolve.collectAllCandidates` disregards
the call's inapplicability and resolves successfully into an
applicable candidate. This is because `CandidateFactory` doesn't make
any guarantees for already inapplicable calls. The fix adds
post-processing to `AllCandidatesResolver` to preserve candidate
inapplicability.
- Most tests that this commit changes had slightly different results due
to type arguments becoming resolvable.
- `wrongNumberOfTypeArguments.kt` and
`wrongNumberOfArgumentsInTypeAliasConstructor.kt`:
`ConeDiagnostic.toFirDiagnostics` prefers specific errors. Because
`ARGUMENT_TYPE_MISMATCH` is specific and `INAPPLICABLE_CANDIDATE` is
not, only the former is reported. I see no reason to pass an illegally
typed argument in either test, so the change reduces the errors to
`INAPPLICABLE_CANDIDATE`.
- `typeAliasSamAdapterConstructors2.fir.kt`: See KT-55007.
- Disable `mismatchTypeParameters` JS backend test due to its handling
of excess type arguments. See KT-55250.
