Title: Provide more TypeInfo for AA allocations

This is needed for precise scanning of heap objects allocated by the AA implementation.

- add _aaGetY with full type info
- supply more type info to _aaValues, _aaKeys
- return normal dynamic array, not "raw" array

I'm not sure how obsolete this becomes with the new AA implementation, though.
