Create Controller for app buttons

These two buttons(uninstall + forcestop) are used in both battery page
and app page, we should move the logic for these two buttons into one
place.

This cl creates the AppButtonsPreferenceController for the above
purpose. This cl only copies the logic to controller but hasn't make
InstalledAppDetails use this controller.

Since DialogFragment could not use function in controller directly,
the controller expose DialogListener and all the fragments must
implement this interface. Then they can delegate the method call
to controller directly.

The following cl will:
1. Make the InstalledAppDetails be compatible to controller
2. Make the InstalledAppDetails use this controller.
