Geo: Route calculators

### Is this feature request related to a new or existing Amplify category?

New category

### Is this related to another service?

Amplify Geo, Amazon Location Service

### Describe the feature you'd like to request

For my use case (automatically scheduling meetings in a calendar), it would be useful to have the route calculators feature provided by AWS Location Service, in order to arrange meetings based on the distance among them.

### Describe the solution you'd like

I would like to use it similarly to other Geo features Amplify provides.

### Describe alternatives you've considered

Connecting directly to Amazon Location Service. Currently, I'm waiting on Amplify to implement this feature in the Geo category.

### Additional context

_No response_

### Is this something that you'd be interested in working on?

- [ ] 👋 I may be able to implement this feature request

### Would this feature include a breaking change?

- [ ] ⚠️ This feature might incur a breaking change

Start by locating the Amplify Geo category entry points and reviewing how existing Geo features integrate with Amazon Location Service. Then determine the route-calculator interface and expected behavior for scheduling meetings by distance; the work is done when route calculators are available through the Amplify CLI's Geo category with suitable validation and coverage.
