[Request feature] Allow bool val for setPermission() methods

[bastien70]

Short description of what this feature will allow to do:
Currently, when configuring a permission for a MenuItem, an action, a crud, or a field, the setPermission() method expects a string or an expression. It would be interesting to also accept a boolean based on conditions

Example of how to use this feature

yield MenuItem::linkToCrud('Administrateurs', 'bi bi-shield-lock', User::class)
            ->setController(AdminCrudController::class)
            ->setPermission($this->isGranted(UserRole::ROLE_SUPER_ADMIN->value) || $this->isGranted(UserRole::ROLE_ENTREPRISE->value));

Here, the permission is validated if the user has the ROLE_SUPER_ADMIN role or the ROLE_ENTERPRISE role.

Here is an example with roles, but it could be something else.

The main reason for this request is that it forces us to create a Voter on purpose for this, which is disruptive.
Or the alternative is currently something like this :

yield MenuItem::linkToCrud('Administrateurs', 'bi bi-shield-lock', User::class)
            ->setController(AdminCrudController::class)
            ->setPermission(new Expression("is_granted('".UserRole::ROLE_SUPER_ADMIN->value."') or is_granted('".UserRole::ROLE_ENTREPRISE->value."')"));

But it's not practical.

Likewise, from CRUD, it will be useful to be able to do the same thing in the configureCrud() method :

$crud->setPermission($this->isGranted(UserRole::ROLE_SUPER_ADMIN->value) || $this->isGranted(UserRole::ROLE_ENTREPRISE->value));

EDIT :

I created a helper which returns me an expression, conforming to my expectations, if it can help some people :

<?php

namespace App\Helper;

use Symfony\Component\ExpressionLanguage\Expression;

class EasyAdminPermissionHelper
{
    /**
     * Returns an Expression that checks if the user has any of the given roles.
     *
     * @param array $roles Array of role strings
     * @return Expression
     */
    public static function isGrantedAny(array $roles): Expression
    {
        $expressions = array_map(
            fn($role) => "is_granted('{$role}')",
            $roles
        );

        $expressionString = implode(' or ', $expressions);

        return new Expression($expressionString);
    }

    /**
     * Returns an Expression that checks if the user has all of the given roles.
     *
     * @param array $roles Array of role strings
     * @return Expression
     */
    public static function isGrantedAll(array $roles): Expression
    {
        $expressions = array_map(
            fn($role) => "is_granted('{$role}')",
            $roles
        );

        $expressionString = implode(' and ', $expressions);

        return new Expression($expressionString);
    }
}

And now :

yield MenuItem::linkToCrud('Administrateurs', 'bi bi-shield-lock', User::class)
            ->setController(AdminCrudController::class)
            ->setPermission(EasyAdminPermissionHelper::isGrantedAny([UserRole::ROLE_SUPER_ADMIN->value, UserRole::ROLE_ENTREPRISE->value]));
