Add MenuContributorBase to check permissions in advance.

Resolve #7788

Usage:
Use GrantedPermissions to check the permissions.

public class TestMenuContributor1 : MenuContributorBase
{
    public TestMenuContributor1()
    {
        PreCheckPermissions.Add("MenuPermission1");
        PreCheckPermissions.Add("MenuPermission2");
    }

    public override Task ConfigureMenuAsync(MenuConfigurationContext context)
    {
        if (GrantedPermissions.Contains("MenuPermission1"))
        {
            //context.Menu.AddItem()
        }

        return Task.CompletedTask;
    }
}

If you think this ok. I will do same changes to IToolbarContributor and apply to all modules and templates.

This solution requires manual work and open to bugs (we may forget to add to the list). Also, it is a solution per menu contributor.

What if we add RequiredPermission to the ApplicationMenuItem. All contributors add menu items without permission checking. Then MenuManager removes items from the menu if user has no permission.
Same logic can be applied to toolbarcontributor.
