Avoid unnecessary tree-sitter reparse when setting the same range

Avoid unnecessary tree-sitter reparse when setting the same range

* src/treesit.h (Lisp_TS_Parser)
* src/treesit.c (make_treesit_parser): Remove has_range field, add
last_set_ranges field.
(Ftreesit_parser_set_included_ranges): Return early if the new range
is the same as the old one.
(Ftreesit_parser_included_ranges): Change has_range to
last_set_ranges.
