vk: Use switch instead of look up table for state transitions.

We currently use a set of pairs to validate state transitions. A much
more lightweight solution is to use the hashes of the transitions.
Since our hash can be computed at compile time, we mark it as constexpr
and use it in a switch statement to verify state transitions.
