[9.x] Added required directive

[erikn69]

Closes #43102

This PR provides the use of the common HTML directive required through a shorthand syntax via a Blade directive. Allowing developers to have a more enjoyable method of required a input, for example, could improve the smooth flow that we Laravel developers are consistently being treated too. Simple yet, effective. Example

 <input type='email' name="email" @required( !auth()->user()->is_admin )>
 <input type='password' name="password" @required( !auth()->user()->is_admin )>

I will add it on laravel/docs if it is merged
