Make sure treesit.el doesn't create parsers by itself (bug#75456)

Make sure treesit.el doesn't create parsers by itself (bug#75456)

Up to this point, functions in
treesit.el (font-lock/indentation/etc) creates a parser if one
doesn't exist.  This doesn't work well with local parsers,
because local parsers are not visible at global level and
font-lock or indentation functions might accidentally create a
global parser for an embedded language.

The solution is to not create parsers automatically.  This has
the potential of breaking things, but I don't expect any actual
breakage: all the major modes create parsers they need in the
major mode body, even though previously it isn't technically
necessary.

* lisp/treesit.el (treesit-buffer-root-node):
(treesit--update-ranges-local):
(treesit-update-ranges):
(treesit--guess-primary-parser): Use treesit-parser-list instead
of treesit-parser-create.
