Change the visual for wildcard string in attribute list

Adds dyngroup to usersGroupsRolesAttribute array.

Fixes an HTML validation error.

issue #6187

In a future version we should move all classes to namespace, but for now
 only moving Attribute class to avoid problems with PHP>=8 which have its
 own Attribute class.

issue #6072

This replaces save_object and execute methods by 3 methods:
readPost - Reads POST data
update - Update object state
render - Render HTML UI

The point is to avoid reading POST and rendering HTML when this is not
 needed (when doing stuff through the webservice for instance).

It’s also more consisent across FD with all classes handling some kind
 of dialog implementing the new interface FusionDirectoryDialog which
 makes sure these 3 methods are implemented.

issue #6072

PHP<7.2 do not like changing typing of the attribute in inheriting
 classes, even if it’s to a larger constraint.

issue #6106

Plugins code will need to be adapted to this change.

issue #6071

This avoids repeating parameters at each call, and makes sure the same
 parameters are used for escaping across fusiondirectory.
This commit also adds escaping in some places where there was none.

This is consistent with ObjectAttribute and the use of management
 classes for the dialog.

Make sure ObjectAttribute, ObjectsAttribute and ObjectSelectAttribute
 behave consistently, making it easier to switch from one to the other.
