New permissions page for app specific permissions

This does not handle All permissions quite yet. This will be handled in
a separate CL.

This change by itself also affects the full permissions page, so it will
not be submitted until other permissions CLs are approved.

This CL also tries to unify the base frame for car related settings
permission controller. Will need to do a separate cleanup CL for default
applications.
