Fix tree-sitter language remapping

Fix tree-sitter language remapping

* src/treesit.c (resolve_language_symbol): Move forward.
(treesit_ensure_query_compiled): Resolve language remapping
here.
(Ftreesit_parser_list): Don't resolve language remaping here,
because there's no need: parsers now carries the remapped
language.
(Ftreesit_query_compile): Don't resolve language remapping here,
because we resolve language remapping when actually compiling
the query.  Also we want the query to carry the unmapped
language.
