[9.x] Add some class rules in class Rule

[michaelnabil230]

It is the best way to call these functions password and imageFile and file, enum.

And don't call in Controller or FormValidation all namespace

Before PR:

use Illuminate\Http\Request;
use Illuminate\Validation\Rule;
use Illuminate\Validation\Rules\Password;
use Illuminate\Validation\Rules\File;
use Illuminate\Validation\Rules\Enum;

class WelcomeController
{
    public function store(Request $request)
    {
        $request->validate([
            'password' => Password::default(),
            'image' => File::default(),
            'status' => new Enum(StatusEnum::class),
            'name' => Rule::requiredIf(function () {
                return true;
            })
        ]);

        // 
    }
}

After PR:

use Illuminate\Http\Request;
use Illuminate\Validation\Rule;

class WelcomeController
{
    public function store(Request $request)
    {
        $request->validate([
            'password' => Password::default(),
            'image' => Rule::file()->default(),
            'status' => Rule::enum(StatusEnum::class),
            'name' => Rule::requiredIf(function () {
                return true;
            })
        ]);

        // 
    }
}

Removed the password one. The rest seems fine.
