Internal: Add Configuration to influence the order of branding features

[ronaldtebrake]

Problem

Right now we don't have an easy way to influence the bottom bar features, while we do promise that.
This was done by implementing a patch, per environment which uses

function hook_social_branding_preferred_features(): array {
  return [
    new PreferredFeature('home', 0),
    new PreferredFeature('events', 1),
    new PreferredFeature('groups', 2),
    new PreferredFeature('search', 3),
    new PreferredFeature('topics', 5),
  ];
}

But than changing that per environment.

Solution

We now provide a new admin form, currently no permissions are set, as it's for now Admin only (until we know every business requirement we need to provide it for SM, e.g. which preferred features are available, mandatory, how many etc)

So this form gives admins a way to deal with the bottom bar features for the App.

Right now we use the existing hook as input for the ConfigForm which preferred features are available.
We add a draggable table to the form, which shows all available features.
And we change the place where the hook is invoked, for GraphQl, to the configuration from the form submitted.

Notes

• We don't provide default configuration, this ensures we don't break existing platforms, by default still the ones provided by the hook hook_social_branding_preferred_features() are available and used
• Once the Form is saved however, that will take presedence, this to ensure we don't have duplicate weights from the Hook and the Form
• The hook_social_branding_preferred_features_alter is still leading, this allows people to always add or remove preferred features.

How to test

• Enable social_branding, see that it works (unit tests also provide this proof)
• As a sitemanager see you can't reach the page
• As admin go to admin/config/opensocial/branding-features
• When saving I expect the Form to have the order you saved it in
• Querying the API clearly shows the new order

Release notes

We have added an Admin form for the Branding features which are used through GraphQL.
