mbedtls: Enable smaller implementation for SHA256/512
Smaller implementation for SHA256 and SHA512 helps to reduce the
ROM footprint though it has a certain impact on performance.
As a trade-off, enable it as a default config when MbedTLS is
enabled can reduce the target size significantly with acceptable
performance loss.
