Abstracting mcuboot crypto functions for cleaner porting and less of an ifdef hell.

- The enc_context needs to initialize.

boot_enc_load seems to always be used to start the process, so calling
init inside makes sense.

- Handle boot_encrypt getting called with size of 0.

- No need to free contexts because Zephyr sets MBEDTLS_PLATFORM_NO_STD_FUNCTIONS.

I don't quite like this because it's implicit and will leak memory on
other ports.
