Add support for showing the user's own status over their avatar on the app's Settings button. (#5912)

* Add a common .inverseMask view modifier and use a blend mode for efficiency.

This also fixes the snapshot rendering 🎉

* Add support for the status emoji on the app's Setting button.

* Align the room header decoration icons with the status emoji.

* Add missing snapshots.
