ASM: Add required AppOp lookup to custom sensors for all permissions.

Previously, we only made an AppOp lookup if the custom sensor used
BODY_SENSORS. We are deprecating BODY_SENSORS in favor of
READ_HEART_RATE and other granular health permissions. This CL ensures
the correct AppOp is used if the custom sensor uses these other
permissions.

In the spirit of flagging, we guard the expanded AppOp lookup behind
the replace_body_sensor_permission_enabled flag. However, it's worth
noting that any permission with an existing AppOp would now be used (not
just READ_HEART_RATE).
