ForegroundService: Include HR, SkinTemp, Spo2 permissions for

health fgs.

We are deprecating the BODY_SENSORS permission in favor of
READ_HEART_RATE, READ_SKIN_TEMPERATURE, and READ_OXYGEN_SATURATION.
As part of this we want to ensure that apps using any of those
permissions are able to start a foreground service for the
"health" type.

Based on feedback from the API council, we are marking the API as a
@FlaggedApi which should ensure our changes aren't reflected until
the flag is flipped.
