[IR] Introduce new IdSignatures

FileSignature, CompositeSignature, LocalSignature

They are needed to make possible reference any non-local declaration via
 signature, including private signature, type parameters and so on.

- Support those new signatures in proto and klibs
- Rename `isPublic` -> `isPubliclyVisible` due to changed semantic
- Fix FIR
- clean up code
