[Migration] Figure out a story for sharing session state with ASP.NET apps

[pranavkm]

As part of #40078, we want to figure out if there is a way to allow a frontend ASP.NET Core app and a backend System.Web based app to share session state.

• Can we support one of the existing session state providers such as SQL Server state provider?
• Could we build a state state provider using IDistributedCache? Is that sufficient for large apps?
• Are there framework components such as MVC's TempDataProvider that need to be investigated for compatibility?
