This change covers the case where some f/o was generated in common module
and it is referenced in platform code. But signature of this f/o may be
different in different modules because of e.g. actualization of value
parameters with actual typealias

Atomicfu compiler plugin supported transformations for K/N:
* atomic properties are replaced with volatile properties and all the operations are delegated to native atomic intrinsics
* atomic arrays are replaced with kotlin.concurrent.Atomic*Arrays
* all other features available on JVM are covered as well (custom atomic extensions, delegated properties, debug tracing)
See (KT-58358, https://github.com/Kotlin/kotlinx-atomicfu/issues/261)

By ignoring type parameters. Since type parameters in annotations are a
very limited feature, their sole use is to be able to specify them as
KClass argument: annotation class Foo<T: Any>(val bar: KClass<T>).
Since we can encounter type param only as a KClass type argument (and
never as a property type), simple approach of ignoring them works fine.
In that case, since we simply copy property types to synthetic
implementation class, its properties in IR start look like this:
annotation class FooImpl(override val bar: KClass<T of Foo>). This IR
seems to be not completely correct, since FooImpl.bar type contains T of
Foo param, which is out of its scope. However, so far I didn't
encounter any problems with this during testing and after MR discussion
this approach has been considered possible.

Implementation is very similar to the `enumValues` intrinsic.
Java enums and old (pre-1.9) Kotlin enums will be supported in a
subsequent commit.

Invocation of atomic intrinsics is only allowed on property references that are known at compile time. This commit makes it possible to also invoke intrinsics on a constant property reference getter passed as an argument.

In early prototypes of interpreter, it was easier to assume that
all classes from Java can be interpreted and fix something if not.
Check for Java declaration was done by checking that the package name is
starting with "java". But this is actually wrong and can lead to errors
when some code is declared in "java" something package, but is not from
Java stdlib.

This is important for IR lowerings like PolymorphicSignatureLowering
which are very sensitive about the correct types of expressions and
placement of coercions to Unit (KT-59218).
A boolean parameter to `insertImplicitCasts` is not the best solution to
ensure that coercion to Unit is added. The best solution would be to fix
the TODO and generate coercion to the block's type for the last
statement. But that will affect many other places and will need to be
done separately => KT-59781.
Code in IrInterpreter is uncommented to fix the FIR test
`compiler/testData/ir/interpreter/exceptions/tryFinally.kt`; otherwise
evaluation of the function `returnTryFinally` there crashes with
"NoSuchElementException: ArrayDeque is empty". No idea why this test
didn't fail for K1 though, since the created IR is exactly the same.
For some unknown reason this breaks WASM backend with K2, but not with
K1 => KT-59800.
This aligns the behavior with K1 and fixes an issue when the default
value was deserialized as FirExpressionStub leading to an exception
in FIR2IR when trying to convert it to an IR expression.

This fixes an issue with checking for default values in call resolution
(see FirDefaultParametersResolver) where it is expected that the map
only contains a single compatible entry.
#KT-59613 Fixed
... for Kotlin-generated classes which do not correspond to a "class"
from the Kotlin language's point of view. For example, Kotlin lambdas,
file facade classes, multifile class facade/part classes, WhenMappings,
DefaultImpls. They can be distinguished from normal classes by the value
of `KotlinClassHeader.Kind` (which is the same as `Metadata.kind`).
Another theoretical option would be to throw exception at the point
where the `::class` expression is used, if the expression's type on the
left-hand side is a synthetic class. But we can't really do that since
it'll affect performance of most `<expression>::class` expressions.
So, construct a fake synthetic class instead, without any members except
equals/hashCode/toString, and without any non-trivial modifiers. It kind
of contradicts the general idea that kotlin-reflect presents anything
exactly the same as the compiler sees it, but arguably it's worth it to
avoid unexpected exceptions like in KT-41373.
In the newly added test, Java lambda check is muted but it should work
exactly the same as for Kotlin lambdas and other synthetic classes. It's
fixed in a subsequent commit.

kotlin-reflect works correctly already for Kotlin-generated local
classes and anonymous objects, but not for Java ones. This is fixed in a
subsequent commit.
