Martijn Coenen e3f1d5a314 Create new mediaprovider_app domain.
This is a domain for the MediaProvider mainline module. The
MediaProvider process is responsible for managing external storage, and
as such should be able to have full read/write access to it. It also
hosts a FUSE filesystem that allows other apps to access said storage in
a safe way. Finally, it needs to call some ioctl's to set project quota
on the lower filesystem correctly.

Bug: 141595441
Test: builds, mediaprovider module gets the correct domain
