Align generic signature for inner classes to work as in Java

#KT-10397 Fixed

According to JVMS (p. 4.3.4) inner classes should be separated with `$` in generic signature.

Note that in Java, inner types separated with `.` after first parameterized type, and now we preserve the same behaviour. See tests for clarification.
