- Reduce usage of 'isUnderStandardKotlinPackages' check in commonizer source code
- Rely on common module dependencies supplied via commonizer Parameters which not only
Kotlin standard library but may also include common fragments of other libraries
1. Drop CirClassifierId
2. Specialized classes for each kind of types (classes, TAs, type parameters, flexible types).
3. TypeCommonizer now returns commonized type. In case of TAs this could be a completely new type
describing expect class or a new TA with the different underlying type.
