Let table AM insertion methods control index insertion

Browse Source 
Previously, the executor did index insert unconditionally after calling
table AM interface methods tuple_insert() and multi_insert().  This commit
introduces the new parameter insert_indexes for these two methods.  Setting
'*insert_indexes' to true saves the current logic.  Setting it to false
indicates that table AM cares about index inserts itself and doesn't want the
caller to do that.
