At the moment, SubclassOptInRequired is marked with the
ExperimentalSubclassOptIn annotation. However, it does not work
as expected due to a missing opt-in error. To use SubclassOptInRequired,
an explicit opt-in is necessary because SubclassOptInRequired is an
unstable feature now.

In before, actualizer was copying attributeOwnerId to new
nodes. This leads to attributeOwnerId linked to non-actualized
node. It's unclear what it leads to, so we just stop doing that.
In particular, if attributeOwnerId references another node,
this information would be lost.

...instead of those computed from a frontend representation
(`symbol.signature`).
This is more robust; besides, we are going to turn off building
signatures from FIR, so `symbol.signature` is going to return null soon.
The error-level enhancement is kept as warning-level and a new
LanguageFeature is introduced to turn the warning into an error.

This is required for EnhancedTypeForWarningAttribute because scopes
should not be reused between cone types with different values of
this attribute.

Changed the code in AbstractNativeCExportTest to create the executable
in the same directory as the dynamic library.
This update is to accommodate the lack of rpath on Windows systems.
FileCheck tests force using dev LLVM distribution. It breaks
invocation of LLVM Clang which tries to look for executable in a wrong
directory. Let's keep things simple and always pass dev variant to our
tests.
Previously, if the parent class was in Java code and the subclass in
Kotlin, the opt-in usage error would not be reported for the subclass.
The problem was that the extractClassFromArgument function couldn't get
the class type from Java code. It was looking for a ConeClassLikeType,
but found a ConeFlexibleType instead.

Without this change, FIR2IR created a symbol for setter of f/o Derived.x,
but IR f/o generator doesn't create a setter in f/o, as this setter is
invisible in Derived

Now, we detect clashing signatures during serialization to KLIB and
report a compiler error if two or more declarations have the same
`IdSignature`
For example, for the following code:
```kotlin
@Deprecated("", level = DeprecationLevel.HIDDEN)
fun foo(): String = ""
fun foo(): Int = 0
```
the compiler will produce this diagnostic:
```
e: main.kt:1:1 Platform declaration clash: The following declarations
have the same KLIB signature (/foo|foo(){}[0]):
fun foo(): String defined in root package
fun foo(): Int defined in root package
e: main.kt:4:1 Platform declaration clash: The following declarations
have the same KLIB signature (/foo|foo(){}[0]):
fun foo(): String defined in root package
fun foo(): Int defined in root package
```
Note that we report this diagnostic during serialization and not earlier
(e.g., in fir2ir) for more robustness, so ensure that we check
exactly the signatures that will be written to a KLIB.
If we later introduce some annotation for customizing a declaration's
signature (e.g., for preserving binary compatibility), this
diagnostic will continue to work as expected.
