[kmac] Unsupported Mode Strength

This commit adds a control knob to enable/ disable further process on
ModeStrength error. In previous design, KMAC always proceeded with the
error to support the KMAC512, cSHAKE512.

Now, the error check module won't hand over the SW issued command if
`en_unsupported_mode_strength` is cleared and unsupported mode and
strength combination has been configured.
