[5.5] Add a validate method onto the request

[JosephSilber]

This will allow calling validate directly on the request object:

$data = request()->validate([
    'title' => 'required',
    'body' => 'required',
]);

A request shouldn't know how to validate itself!!!11!!one!!!!!111!!eleven!!111!!elf!!

I don't understand the point of this

I'm very much in favour of this. I've been doing this with macros for quite some time:

public function registerValidate()
{
    Request::macro('validate', function ($rules, $messages = [], $customAttributes = []) {
        (new class() {
            use ValidatesRequests;
        })->validate($this, $rules, $messages, $customAttributes);
    });
}

Which, as you can see, it takes a little magic when done as a macro, so having this built in gets a big 👍 fro me.

Hmm, I guess I could have use the validator() trick. Interesting.

Why didn't this go to the request object? :)

@gocanto Laravel's components are decoupled from each other as much as possible. You should be able to pull in only some of its components into a non-Laravel project, and have it work without pulling in all of the framework.

Since the Request class lives in the Http component, it doesn't have access to the validator, which lives in the Validation component.

In addition to all of the standalone components, Laravel has a separate Foundation component that serves as the glue between all other components for when you're using the full laravel framework. This Foundation component is tightly coupled to all of the other components, so it has access to both the request class and the validator. This makes it the perfect place to hook up validation with the request 👌

@JosephSilber Excelente. Thanks for the explanation!
