Vector AES encryption final round with scalar

Performs the final round of AES encryption on vector register vs2 using scalar register rs1, storing results in vector register vd according to mask vm. This combines the shift rows, sub bytes, and add round key operations.

This instruction must have data-independent timing when extension Zkt is enabled.
