psa: cipher: Dispatch based on driver identifier

Browse source 
For cipher multi-part operations, dispatch based on
the driver identifier even in the case of the
Mbed TLS software implementation (viewed as a driver).
Also use the driver identifier to check that an
cipher operation context is active or not.

This aligns the way hash and cipher multi-part
operations are dispatched.
