sensorservice: Add retry logic for ISensors acquisition

Address a race condition where the sensors HAL may crash after the
binder is retrieved but before the ISensors interface is acquired,
leaving the sensor service in a broken state.

This change introduces a retry loop to make the connection more robust.
If the connection still fails after all retries, the service will
intentionally crash via a CHECK, allowing for recovery through a service
restart.
