Provide wrapper for monitoring satellite capabilities change.

Add wrapper API to provide a way to call registerForSatelliteCapabilitiesChanged/unregisterForatelliteCapabilitiesChanged.

Bug: 307821402
Test: manual
  1. push updated SatelliteClient.jar into /system_ext/framework/
  2. run SatelliteTestApp to check whether correspondent APIs in SatelliteManager called as expected.
