Follow-up of https://github.com/odoo/odoo/pull/154349

PR above allowed to define shadow DOM-specific overlays, which is desirable for apps that need to work in a shadow DOM like livechat from visitor's perspective.

The reason for shadow DOM is to use exactly same style and behaviour of livechat like in Discuss as internal users. The shadow DOM has to sustain its good working by itself, so it also needs to deploy some required main components like overlay container. In website, there's also an overlay container, and since they share the same stateful service (overlay_service), we do not want to display the overlay twice.

So PR above solved the issue by allowing to make overlay with a provided `rootId`, which when set it contains the `id` attribute of the root node of the overlay that has to manage the overlay. This allows to clearly determine which overlay container is responsible to display the appropriate overlay.

Code above was however buggy: it relies on `isVisible(overlay)`, whose computation requires `rootRef.el`. Refs' el are not determined on the 1st rendering of the overlay service. This is not a problem when the overlay container is 1st mounted without any overlay, but if it's being registered with some overlays, mounting the overlay container afterwards results in the non-showing of the overlay. The `rootRef` is important to find out the "global" root node id, i.e. the shadow DOM root id.

This commit fixes the issue by rendering again overlay container after mount when there are some pre-registered overlays.

## [FIX] project: let project user to set a project as favorite

Before this commit, since the project user cannot edit a project and a
recent fix (https://github.com/odoo/odoo/pull/168464) ensures the boolean_favorite widget is readonly is the field
is readonly or if the record is readonly then the project user can no
longer mark a project in favorite.

This commit overrides the standard widget `boolean_favorite` for project
to make sure the widget is always editable if the field is not in
readonly.

## [FIX] lunch: allow employee to save as favorite a product in lunch

Before this commit, the current user could have no access to lunch app
to add/edit product, etc. Since the user cannot edit `lunch.product`
model, he can no longer save as favorite a product since a recent bug
fix (https://github.com/odoo/odoo/pull/168464) to ensure the button is in readonly when the field or the record is
in readonly.

This commit makes sure the user can always save as favorite even if the
record is readonly for the user since the user just has to choose what
he would like to eat during lunch break and so he just needs to select
and save as favorite.
