refactor(measured-boot): add generic macros for using Crypto library
It doesn't look correct to use mbed TLS defines directly in the Event
Log driver as this driver may use another Crypto library in future.
Hence mbed TLS Crypto dependency on Event Log driver is removed by
introducing generic Crypto defines and uses those in the Event Log
driver to call Crypto functions.
Also, updated mbed TLS glue layer to map these generic Crypto defines
to mbed TLS library defines.
