The proposed defcustom 'treesit-enable-modes' was supposed to have such
:set that would compare the old with new list of customized modes, then
for added modes like 'c-ts-mode' it could call (treesit-enable 'c-ts-mode),
and for removed modes (treesit-disable 'c-ts-mode).

Then for modes whose entries already exist in auto-mode-alist,
it will add/remove a mapping in major-mode-remap-alist.
For modes without an entry in auto-mode-alist, it will
update auto-mode-alist.
