React to dotnet/runtime#47684, a new transport package (#30405)

* React to dotnet/runtime#47684, a new transport package
  - handle Microsoft.Extensions.Internal.Transport -> 'Microsoft.AspNetCore.Internal.Transport name change
  - remove `$(...V0Version)` / `%(RTMVersion)` workarounds
  - remove mention of System.Security.AccessControl package; only need transitive references to that
  - confirm content of Microsoft.AspNetCore.Internal.Transport package
    - missing Microsoft.Extensions.DependencyModel assembly

* Remove unnecessary `using`s
  - namespace previously available due to Microsoft.Extensions.Internal.Transport dependency
  - no need for Microsoft.AspNetCore.Internal.Transport dependency

* nit: Clean up "Extensions" naming in Ref project

* Correct targeting pack content
  - intersection w/ `@(ExternalAspNetCoreAppReference)` items added nothing
  - excluded assemblies now included in transport package

-    these assemblies must not change. Must also compile our assemblies against the initial ref/ assemblies for runtime
-    packages. But, need to test against the latest implementation assemblies and ship them in our shared framework.
-    Upshot is we need Major.Minor.0 runtime packages for compilation and the targeting pack and Major.Minor.Latest
-    runtime packages for everything else. This is not an issue for assemblies available in Microsoft.NETCore.App.Ref or
