Replace jQuery UI sortable with Sortable js

We are in the process of deprecating jQuery UI in core. The jQueryUI sortable library is among the components that need to be removed/replaced.
As mentioned in the parent issue: #3067261: [Plan] Remove jQuery UI components used by Drupal core and replace with a set of supported solutions
The OpenJS Foundation lists jQuery UI as an Emeritus project in https://openjsf.org/projects/ which is described as:

Emeritus projects are those which the maintainers feel have reached or are nearing end-of-life

3 of Drupal core's modules currently depend on jquery.ui.sortable

Sortable https://github.com/SortableJS/Sortable was chosen because it seems popular (in terms of github stars and forks), is actively maintained (looking at recent issue fixes and releases), and the comparison video looks impressive.
Switch ckeditor, media_library, and layout_builder to use the replacement library.
Deprecate jquery.ui.sortable (e.g., emit a deprecation notice for modules/themes that depend on it).
Deprecate jquery.ui.touch-punch which is only used by jquery.ui.sortable in media_library.

Sortable has a different JS API than jquery.ui.sortable. We still need to decide whether we need to provide a bridge/façade, or whether it's ok to require contrib modules to change their JS code to the new API.
A contrib module providing the jquery.ui.sortable asset library could also be created
