We need to automatically resolve group membership into a boolean
for theme object type settings which are of the group type, similar
to what we did in the original commit above for group list type
settings.
This behaves in the same way -- for an object setting schema like this:
```
menu_sections:
type: objects
default:
- name: section 1
groups:
- 1
- 3
schema:
name: menu section
properties:
name:
type: string
groups:
type: groups
resolve_group_membership: true
```
We replace `groups` with a boolean `user_in_groups` (groups is just
the property name, it could be foo_bar etc.) and then you can
do this on the client:
```
for (const section of settings.menu_sections) {
if (section.user_in_groups) {
// User is in at least one selected group for this section.
}
}
```
Rather than inspecting the `currentUser.groups`, which only includes
visible groups, not all groups the user is a member of. This allows
for more accurate permission checks for theme settings that are group
based.
Also c.f.
