Implement ScreenRecordingService to record provided capture target. 

This is a thin service that will be running in the user process on hsum
enabled devices. It doesn't have the burden of the whole System UI
dagger graph meaning it's significantly cheaper to start.

It should delegate the majority of its functionality back to the System
UI using aidl interfaces.
