Merge #9180

9180: fix: fix some IDE functionality inside attribute macros r=jonas-schievink a=jonas-schievink

In `SourceToDefCtx::find_container`, we might encounter a container that has an attribute macro. We need to skip that item, instead of bailing out and creating an empty `Resolver`, otherwise all names in the macro stay unresolved.
