fix(ivy): i18n - remove translate function when clearing translatio…

…ns (angular#34346)

The `loadTranslations()` function will attach the `translate()` function
to `$localize.translate` to cause runtime translation to occur.

We should cleanup after ourselves by unattaching this function when
we call `clearTranslations()`.

Fixes angular#32781
