[13.x] Add callRoute() to MakesHttpRequests trait

[shaedrich]

Motivation

Currently, when you have a route like this:

Route::get('users', [UserController::class, 'all'])->name('users.all');
Route::delete('users', [UserController::class, 'delete'])->name('users.delete');

And you write a HTTP test for your functionality behind this, you can easily mess this up like this:

public function testUsersAll()
{
    // ✓ valid, but should be either GET + users.all or DELETE + users.delete
	$this->get(route('users.delete'));
}

callRoute() links calling routes in tests with retrieving routes so that they can be validated:

public function testUsersAll()
{
    // ✓ valid, but should be either GET + users.all or DELETE + users.delete
	$this->callRoute('users.delete', method: 'GET'); // × Throws
}

Future scope (intentionally left out)

• Dedicated methods (make the method validation more useful)
  • callGetRoute(), callPostRoute(), callPutRoute(), callPatchRoute(), callDeleteRoute(), callOptionsRoute()
  • callJsonRoute(), callJsonGetRoute(), callJsonPostRoute(), callJsonPutRoute(), callJsonPatchRoute(), callJsonDeleteRoute(), callJsonOptionsRoute()
• Parameter validation
