[atomicfu-JVM] Preparation for commonization of JVM and K/N transformers

The following updates in the JVM/IR plugin were made:
* Lots of refactoring with preparation for K/N support: commonization of transformations.
* Improved error handling (checks for visibility constraints, appending message about usage constraints in case of an error).
* Explicit requirements for the visibility of atomic properties: to prevent leaking they should be private/internal or be members of private/internal classes.
* Fixed visibility of generated properties: volatile properties are always private and atomic updaters have the same visibility as the original atomic property.
* Volatile fields are generated from scratch and original atomic properties are removed.
* Delegated properties support is fixed (only declaration in the same scope is allowed).
* Non-inline atomic extensions are forbidden.
* For top-level atomics: only one wrapper class per file (with corresponding visibility) is generated.
* Bug fixes.
