Support Link/Unlink Cicam to Frontend in Tuner HAL 1.1

The previous linkCicam API does not support local transport stream id
return. Added the support in this CL.

Also added an unlink API to unlink the cicam when needed.

INVALID_LTS_ID will be used on failed operation of linkCicam
and in Tuner java framework as the default value

Test: make android.hardware.tv.tuner@1.1-service
