Validate state on options change

[mikejolley]

Validates the value of the state against the current list of states to ensure it's valid.

Fixes #4753

Testing

How to test the changes in this Pull Request:

1. Setup base location to have a state (US Address)
2. Checkout with a NZ address
3. Do not select a state during checkout. Ensure you can place the order.

This was broken before because the customer would inherit the default store state. E.g. AL (Alabama, US). When checking out from New Zealand, AL would be preserved, but since state is optional, there is no event triggered to update AL to something else. AL is not a valid state for New Zealand.

Changelog

Fix state validation if base location has a state, and the address has an optional state.
