Nikolay Lunyak a9343aeb7d [FIR] KT-55840: Ensure everything actually works
This inconsistency is present due to not using the `// WITH_STDLIB`
in the above tests. When K1 creates the enum, it tries to generate
`entries()`, and for that it tries to load `kotlin.enums.EnumEntries`,
but this is actually an unresolved reference. K1 silently swallows it,
and proceeds.

The reason K2 doesn't fail is that in order to generate `entries()` it
simply creates the necessary `ConeClassLikeType` with the desired
`classId` instead of loading the whole `ClassDescriptor`.

The reason we can still observe `$ENTRIES` and `$entries` in K1
is because they are generated during the JVM codegen, and it
only checks if the `EnumEntries` language feature is supported. It
doesn't check if the `entries` property has really existed in IR
(by this time it's expected to have already been lowered to the
`get-entries` function - that's why "has ... existed").

The reason why the codegen doesn't fail when working with
`kotlin.enums.EnumEntries` is because it creates its
own `IrClassSymbol`.
