[13.x] Add an option to disable device code grant

[hafezdivandari]

Fixes #1836

This PR adds an option property to the Passport class that allows disabling the "Device Code" grant. This is useful in applications where the grant is not needed, allowing you to avoid registering its routes, views, and enabling the grant unnecessarily.

You may disable this grant by adding the following line to the boot method of your application's AppServiceProvider class:

Passport::$deviceCodeGrantEnabled = false;
