Add Support for API keys in Geo resources

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

New category

### Is this related to another service?

GEO

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

As of now, when using geo resources by running `amplify add geo` command , having a cognito resource is mandatory, as the CLI mentions below message :

` geo category resources require auth (Amazon Cognito). Do you want to add auth now? `

However Location Service supports using API keys to access Maps and Indexes :

It would be great to have this feature in Amplify as well.

### Describe the solution you'd like

Allow multiple auth modes in Geo , like GraphQL as well. When adding geo, an option to select authorization modes would be great.

### Describe alternatives you've considered

If there is any workaround to this, please share the same here.

### 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 with the `amplify add geo` command flow and review the linked Amazon Location Service access documentation. The feature is done when Geo resources can offer selectable authorization modes, including API keys and Cognito, without requiring a Cognito resource.
