Implement Country/State select ability (higher priority)

[kasugaijin]

We currently use city-state gem to get a list of states for a given selected country. However, this gem is not reliable in production and this thread does not inspire confidence in the long run. So, we will keep things simple and roll our own. This is currently affecting the production app, so would be great to resolve sooner than later!

This is a two-part issue

Part 1)

• remove the city-state gem
• remove the routes for countries and states
• remove the states controller and its associated view
• remove states tests

Part 2)

• we only use the country and state form fields for the Organization. This is on two forms (organization settings staff/organization/edit and organization account request organization_account_request/new)
• update the form selects so countries options are Canada, USA, Mexico (only these for now)
• states - use stimulus to dynamically update the state select to only show the values for the states of the selected country. So, if I select USA, it updates the State select to show USA states.
• States should be displayed with their full name e.g. California, but saved with their abbreviation CA

Tip: To get a full list of the states for each country, use the city-state gem in your rails console to get the values i.e., CS.states(:US) will give you the states for USA. Then you can use these in Stimulus.

FYI, @sarvaiyanidhi:

Just merged #1169 which added some city-state usage in the fosterer edit form and fosterer invite form. It also touched the country_state_controller.js a little. Hopefully, it's not too much work for you. Thank you!

Thanks for the heads up @mononoken .. Will check this form as well while implementing the changes.
