Move queryjumble.c code to src/backend/nodes/

This will ease a follow-up move that will generate automatically this
code.  The C file is renamed, for consistency with the node-related
files whose code are generated by gen_node_support.pl:
- queryjumble.c -> queryjumblefuncs.c
- utils/queryjumble.h -> nodes/queryjumble.h

Per a suggestion from Peter Eisentraut.
