SurfaceControl: add setAllowedDisplayConfigs

expose ISurfaceComposer::setAllowedDisplayConfigs to SurfaceControl.
This API is expected to be called by DisplayManager depends on the
current policy in place. Once setAllowedDisplayConfigs is called,
SF can only set a new display config if it is part of the allowed
configurations list.

Test: call setAllowedDisplayConfigs() from SurfaceControl and
observe config change.
