Use regex names for EVS HAL implementations

This change deprecates EvsEnumeratorHw, which has been a name for
EVS HAL Enumerator implementations, and uses regex names for them.

New method, isHardware(), is added to IEvsEnumerator and the clients
should use this method to tell whether current service is EVS manager
or driver.
