[Select] customize item equality check

[giladgray]

See #1325 (comment) for original discussion.

Will need to support custom item equality. We cannot rely on === because it immediately falls apart if user creates new objects in each render (a very common React pattern).

Please ensure that the customized equality check is used consistently throughout QueryList, Select, and MultiSelect for both active item and selected item detection.

Is there any estimate for when this will be completed/released? I need to decide whether to wait for this enhancement, or put effort into building a wrapper component that supports dealing with converting values to strict-equality-compatible representative primitives under the hood.

I don't know how I caused this to be unassigned to @brieb

I only added a comment...

@UselessPickles no timeline here. happy to review a PR if you're interested in building this out.
