Propagate configuration change into QSFragmentCompose view

For some reason some configuration changes are not properly being passed
into the NotificationShadeWindowView after a particular sequence of
events:
1. Increase font size
2. Increase display size
3. Decrease font size
4. Decrease display size

This causes the compose view to not have the most up to date
configuration and showing wrong state.

Instead, propagate the configuration change on the fragment that is sent
from FragmentHostManager into the view (bypass the view hierarchy). This
would cause, at worst, a double call to configuration changes in the
ComposeView, but it should be deduplicated as the config value is the
same.

Test: manual, perform steps and open shade
