Add function for removing arbitrary nodes in binaryheap.
This commit introduces binaryheap_remove_node(), which can be used
to remove any node from a binary heap. The implementation is
straightforward. The target node is replaced with the last node in
the heap, and then we sift as needed to preserve the heap property.
This new function is intended for use in a follow-up commit that
will improve the performance of pg_restore.
