Adding controllers for Controls

This CL adds the following controllers for dealing with Controls in
SystemUI:

* ControlsController - Handles favorites and communication with other
controllers
* ControlsBindingController - Handles binding to the different services
and comunication with them.
* ControlsProviderLifecycleManager - Handles binding with one service
and forwards API calls to it.
* ControlsListingController - Handles finding and listing apps that
satisfy the service requirement

Additionally, this CL adds first versions of the management screen to
add or remove favorites. These are persisted.

To enable:
* adb shell settings put secure systemui.controls_available 1
* restart

To launch management activity:
* Enable controls
* adb shell am start
com.android.systemui/.controls.management.ControlsProviderSelectorActivity

Missing from this CL:
* Multi user support
* Documentation in the controller classes
* Graceful rebinding
* Throttling of Binder calls
* Better dumps

Test: atest com.android.systemui.controls
Test: manual testing of favorite management activities
