LibOverride: Add an 'post apply' callback to IDTypeInfo.

Currently this is needed to properly tag PointCache's for info update
(fixes an issue reported in T82503).

Suspect we may need this in more cases in the future though, RNA
assign/update processes are not always 100% enough to deal with
complicated corner cases.
