Add direct APIs for Http.Sys extensions currently using IHttpSysRequestInfoFeature

We previously only exposed a ROM for `IHttpSysRequestInfoFeature` since underlying data structure in Http.Sys were still subject to change. Given that the underlying API is now stable (as I understand based on the Windows API docs), we should replace this feature in favor of a feature with typed-data.

Checklist to track exposing the data via explicit APIs:
