Add treesit-transpose-sexps (bug#60128)
We don't really need to rely on forward-sexp to define what to
transpose. In tree-sitter we can consider siblings as "balanced
expressions", and swap them without doing any movement to calculate
where the siblings in question are.
* lisp/simple.el (transpose-sexps-function): New defvar-local.
(transpose-sexps): Use the new defvar-local if available.
(transpose-subr): Check whether the mover function returns a cons of
conses, then run transpose-subr-1 on the position-pairs.
* lisp/treesit.el (treesit-transpose-sexps): New function.
