Doug Parker 90165b17bc refactor(devtools): refactors property view drag-and-drop behavior (#60286)
The main goal of this change is to remove `categoryOrder` which effectively hard-codes the supported length of `panels`. Adding another item to `panels` is not rendered unless that is added to `categoryOrder`.

My solution to this is to make the set of categories a signal, with each category able to produce the data inside it. This allow `CdkDragDrop` to rearrange categories but then still produce the correct data in the template without needing a separate array to track order.

Also removed `hidden` and inlined it in the template, since the logic was the same for every panel.

`moveItemInArray` is unfortunately an in-place move, so I needed to manually clone the array to ensure `panels` observes an immutable update which works better with signals and change detection.

Angular DevTools UI

This module exports the Angular DevTools component. We render the DevToolsComponent within an Angular application running in Chrome or Firefox DevTools. This module of the application communicates with the Angular DevTools "backend".
