[Raw FIR] Keep the name of an anonymous object of enum entry in classId of its nested classes

It is needed to have an ability to distinguish those two cases in FIR2IR:

Without this change the following tests fail:
- org.jetbrains.kotlin.test.runners.codegen.FirPsiBlackBoxCodegenTestGenerated.Enum
  - testEnumEntryReferenceFromInnerClassConstructor1()
