[api-minor] Add support, in getMetadata, for custom information dictionary entries (issue 5970, issue 10344) (#10346)

Browse source 
The custom entries, provided that they exist *and* that their types are safe to include, are exposed through a new `Custom` infoDict entry to clearly separate them from the standard ones.

Fixes 5970.
