Some unknown difference between `loaddefs-generate` (Emacs 29+) and
`make-directory-autoloads` (<=28) causes evil-pinyin's autoloads file to
throw an error in 29+ when loaded, complaining about missing macros
defined by its dependencies (mainly `define-namespace` and
`evil-define-*`). Specifically, void-function errors.
Since the package is loaded almost immediately on startup, evil-pinyin's
autoloads file isn't needed in the first place, so by disabling it, the
error is resolved. This'll do until I can find a better solution or, at
least, the right party to report it to.
