Subject: feat(heex): borrow matchit support from html (#12717)

* feat(heex): borrow matchit support from html

Makes % support behave the same in heex as in html. For example, quickly moving the cursor between opening and closing tags.

* Remove unnecessary line; define b:undo_ftplugin first

* Remove b:html_set_match_words
