[dv/prince] hit additional toggle coverpoints

This PR adds some very minor changes to the prim_prince testbench to hit
some missing toggle coverage relating to `rst_ni` and `valid_i`:
- `rst_ni`: now both toggles (1->0, 0->1) are hit, no functional impact.
- `valid_i`: we now hold off on raising the `valid_i` input until all
  data/key inputs have been provided to ensure the DUT doesn't start
  encryption/decryption until `valid_i` is signaled.
