[4.x] Support using closures for Statamic route data

[arthurperton]

I love how these Statamic routes are so concise compared to using custom controllers. This PR adds the ability to use a closure for the data argument. So besides this

Route::statamic('uri', 'view', ['foo' => 'bar']);

you can now also do this

Route::statamic('uri', 'view', function () {
    $bar = gatherDataExpensively();

    return ['foo' => $bar];
});

what about this?

Route::statamic('things/{thing}', 'things.show', function($thing) {
    $thing = getThing();
    return compact('thing');
});

Not sure what you're asking.

In laravel, when you use route parameters, they are passed as parameters to the closure. When I use Route::statamic with route parameters, they are not.

I guess my example didn't make much sense now that I read it. Maybe this clears it up.

Route::statamic('things/{id}', 'things.show', function($id) {
    $thing = getThing($id);
    return compact('thing');
});

Oh yeah sorry now what you said seems obvious. 😊
