Add ILFieldInfoIsUnseen and EventInfoIsUnseen functions to filter obsolete IL fields and events from completion, matching existing behavior for methods and properties. Also update ItemIsUnseen to handle ILField and Event items. Fixes #13693 Agent-Logs-Url: https://github.com/dotnet/fsharp/sessions/1d21d452-3f55-4d56-898c-0b50980050b5 Co-authored-by: abonie <20281641+abonie@users.noreply.github.com>
Fix issue number to #13512. Add ObsoleteMembersClass to CSharp_Analysis with obsolete and non-obsolete members. Add 6 C# interop completion tests verifying all obsolete member types are consistently hidden.

Fix an inconsistency where FCS code completion shows some obsolete members (IL fields and events) but hides others (methods and properties). All obsolete members are now consistently hidden from completion by default, respecting the
SuggestObsoleteSymbolsoption.Root Cause
ResolveCompletionsInTypeinNameResolution.fsfiltered obsolete methods (viaMethInfoIsUnseen) and properties (viaPropInfoIsUnseen) but had no equivalent filtering for IL fields or events. This caused obsolete fields and events from C# assemblies to appear in completion while obsolete methods and properties were hidden.Changes Made
AttributeChecking.fs/.fsi: AddedILFieldInfoIsUnseenandEventInfoIsUnseenfunctions, following the same pattern as existingPropInfoIsUnseenandMethInfoIsUnseen. Both handle IL, F#, and type provider cases.NameResolution.fs: Applied the new filtering functions inResolveCompletionsInTypefor events and IL fields. Also updatedItemIsUnseento handleItem.ILFieldandItem.Eventfor defense-in-depth on other completion paths.CSharpClass.cs: AddedObsoleteMembersClasswith obsolete and non-obsolete static fields, methods, properties, and events for C# interop testing.Checker.fs: AddedgetCompletionInfoWithCompilerAndCompletionOptionshelper to support completion tests with external assembly references.CompletionTests.fs: Added 8 new tests:[<Obsolete; CLIEvent>])11.0.100.md.Testing
