AA: implement annotation argument value.

* implemented reading annotation arguments declared in Kt source.
* implemented annotation default value reading for Kt sources.
* implemented function local declarations.
* refactored `KSType.declaration` for better handling local classes.
* refactored `KSClassDeclaration` implementation to use more abstract KtSymbol.
* split annotationValue tests into kotlin and java.
* unmutes annotationValue_kt test.
