  1. zvk: Check VR index alignment constraint and vm constraint 

    The vector specification requires aligning the VR index regarding the
LMUL. Also, it requires that vd cannot be v0 when masking.

Although the vector crypto specification does not explicitly state those
two constraints, the deriving extension should include the general
constraints from the vector specification.

This commit checks the VR index and vm constraints on Zvk instructions.
