[Form Refactor] Request a call page

[luacmartins]

Coming from the New Expensify Forms design doc, we should refactor RequestCallPage to use the new form component, follow the guidelines below:

Here's an example of a Form refactor: #9056

Guidelines

1. Replace the form component with Form.js.
2. Create a unique Onyx key in ONYXKEYS.FORM and pass it as the formID prop to Form.
3. Pass a validate callback prop.
4. Pass an onSubmit callback prop that calls the API via an action.
5. Update all inputs wrapped by Form, following the guidelines in Refactor inputs.
6. Remove any unused code.

Testing

Verify that:

• UI looks as it did before the refactor
• Values can be added and edited
• Errors are highlighted correctly (input border)
• Error messages show up correctly
• Draft values are saved properly
• Form alerts are displayed correctly
• Clicking the fix the errors link focuses the first input with error
• No duplicate submission of the form occurs (when it's already submitting)
