Allow table AM tuple_insert() method to return the different slot

Browse Source 
This allows table AM to return a native tuple slot even if
VirtualTupleTableSlot is given as an input.  Native tuple slots have knowledge
about system attributes, which could be accessed in the future.
table_multi_insert() method already can modify the input 'slots' array.
