[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. The corresponding tickets: https://github.com/Kotlin/kotlinx-atomicfu/issues/322 KT-60528 Merge-request: KT-MR-10579 Merged-by: Maria Sokolova <maria.sokolova@jetbrains.com>
