Make the Group Predicate Available in the AEM UI

[#1]

Request for Feature Enhancement (RFE) Summary:
Use-case:	Summary: Walmart data custodians continue to expand our metadata usage within AEM Assets, and it is necessary to reflect those metadata fields in custom search forms. Currently, adding new metadata fields to the custom search interface requires code-level updates, as we are using the Group Predicate option to consolidate search facets into a dropdown. This slows down iteration and limits the ability of administrators to maintain and evolve search functionality in step with schema updates.
Current/Experienced Behavior:	The Group Predicate (dam/gui/coral/components/admin/customsearch/searchpredicates/grouppredicate)—which is essential for logically grouping and structuring search filters—is not available through the AEM interface for manual configuration. While this predicate can be added through code, it cannot be added or preserved directly through the UI, leading to our business admins not being able to directly change the search form.
Improved/Expected Behavior:	Requested Enhancement: 1. Make the Group Predicate Available in the AEM UI Users can add filters within group predicates Administrators can specify the title of the group predicate in the UI. The search form editor interface allows admins to specify whether the group predicate is initially open or closed for users.
