[FIR] Initialize public visibility for class-like declarations at FIR building phase if no modifier is presented

Java resolving subsystem requires calculated visibility for correct disambiguation of supertypes.
But visibility remains `Unknown` for Kotlin class-like declarations during supertypes resolving because `STATUS` resolve phase is performed after `SUPER_TYPES` phase.
To fix the problem, the visibility should be initialized to public at the FIR building phase if no modifier is presented.
