Hooks on treesit parse refresh

Hooks on treesit parse refresh

[Abin Simon]

I was adding support for builtin treesit to one of my packages,
scopeline.  https://github.com/meain/scopeline.el

The package makes use of these hooks in elisp-tree-sitter to run when a
tree-sitter tree refresh has happened:
- tree-sitter-after-first-parse-hook
- tree-sitter-after-change-functions

I was going through treesit code, but could not find anything
similar. `treesit-explore' seem to add a hook to `post-command-hook' but
wanted to check if there was something more specific that I could use
instead.

The closest API in Emacs 29 is the concept of Tree-sitter notifiers.
Read the documentation of function treesit-parser-add-notifier and
friends.

If this API is not sufficient for what you are trying to implement, I
suggest you open a feature suggestion by sending an email to
bug-gnu-emacs@gnu.org

Thanks.
