Move the heapam index fetch callbacks (index_fetch_begin, index_fetch_reset, index_fetch_end, and index_fetch_tuple) into a new dedicated file. Also move heap_hot_search_buffer over. This is a purely mechanical move with no functional impact. Upcoming work to add a slot-based table AM interface for index scans will substantially expand this code. Keeping it in heapam_handler.c would clutter a file whose primary role is to wire up the TableAmRoutine callbacks. Bitmap heap scans and sequential scans would benefit from similar separation in the future.
