Debugging: Update dictionary debuggers in aspnetcore to follow the new standard

[JamesNK]

dotnet/runtime#92534 updates dictionaries to display the key in the name instead of an index.

We should update name/value collections in ASP.NET Core to follow the same pattern.

There are a lot of custom dictionaries to update:

• ItemsDictionary
• FeatureCollection
• QueryCollection
• HttpHeaders
• HttpContext features
• ModelStateDictionary
• DynamicViewData
• RouteValueDictionary
• HeaderDictionary
• RequestCookieCollection
• ViewDataDictionary
• TempDataDictionary
• QueryCollectionInternal
• HeaderCollection
• RouteData
• ServerAddressesCollection
• RequestHeaders

Hey @JamesNK, I would like to work on this update. Can you assign the issue to me.

[JamesNK]

@shiladitya-mukerji-22 I suggest you start with one or two collections, establish a pattern that can be reused, and then create a PR.

A small PR lets us review it and suggest changes. Once it is good, you or something else can apply the changes to all of the collections.

@shiladitya-mukerji-22 Do you still plan to look at this? If not, I wouldn't mind making these changes.

I'm going to look at this next week.
