Remove treesit-settings

Remove it since we are using separate major modes for tree-sitter and
native variant now.

* doc/lispref/parsing.texi (Tree-sitter major modes): Update manual.
* lisp/treesit.el (treesit-settings): Remove option.
(treesit--setting-for-mode): Remove function.
(treesit-ready-p): Don't check for user preference in treesit-settings.
