[IMP] portal: add support for .closest modifier

It is sometimes useful in practice to be able to configure the portal so that it looks for a target as close as possible as the portal location. For example, in odoo, a portal may be set up in a form view that should target the current form view. But if the form view itself is in a dialog, it may fail, because it may find a valid target in the form view that is located underneath. With this commit, we add a .closest modifier to the `t-portal` directive.
