We've muted some irText tests on JS in the previous commits because
test expectations in some tests are different when targeting JS.
AbstractKlibJsTextTestCase tests use a different logic:
they compare the dump of the deserialized IR with the frontend-generated
IR, not with the expectations in text files, thus muted tests weren't
actually failing.
Here we introduce a temporary fix, namely
a separate // IGNORE directive for klib tests.
When klib tests are moved to the new test infrastructure, there will be
no need to do this.
Fake overrides are needed at least for static fields inherited from Java
interfaces. Not static methods though, because they are not inherited.

We can't reduce resolve to COMPILER_REQUIRED_ANNOTATIONS phase for
annotations with arguments, because currently they don't have
argument mapping
```stracktrace
org.jetbrains.kotlin.utils.KotlinExceptionWithAttachments: By now the annotations argument mapping should have been resolved

- This optimization applied to LL FIR can be extended to K2 as a whole.
Likely, there won't be any performance benefits in CLI runs, but it's
still better to avoid useless symbol providers.
- Dependency symbol providers contained a lot of useless
`FirExtensionSyntheticFunctionInterfaceProvider`s, because such a
provider only generates function classes from compiler plugins. If
there aren't any such `FunctionTypeKind`s in the session, there is no
need to even add the provider.
- `FirExtensionSyntheticFunctionInterfaceProvider`s that are added to
the list of dependency providers despite this optimization will now be
combined in `LLFirCombinedSyntheticFunctionSymbolProvider`. It checks
`ClassId` heuristics once, which is more efficient than checking them
in every provider separately.
- Similar to the implementation of `isNameForFunctionClass` in
`FirSymbolProvider`, `FirSyntheticFunctionInterfaceProvider` benefits
from checking the `ClassId` for a digit before accessing its class
cache.
