Switch to use cursor API in treesit.c
ts_node_parent has bugs (bug#60054), using cursor API avoids that.
Tree-sitter's author might remove ts_node_parent in the future, so
might as well switch to use cursors now. We are basically
reimplementing some of the logic of ts_node_prev_sibling and
ts_node_parent in the sibling helper and cursor helper functions.
