* Fixup reference to Microsoft.AspNetCore.Components.WebAssembly.HttpHandler
As part of attempting to fix the reference in the test project (which ultimately wasn't needed), I messed up the package reference in the WebAssembly package
This fixes the package reference and removes unnecessary code from the test project
* Now works on ns2.1, but links too much
* Now only link System.* assemblies
* Clean up. Also link Microsoft.Extensions.* now too, since it works.
* x-plat slash consistency
* Change all Blazor.* projects to netstandard2.1
* Further TFM updates
* Stop linking Microsoft.Extensions for now, since it requires a more detailed treatment to avoid breaking things
* Add empty Authorization src and test projects
* Add references
* Move auth types into .Authorization project
* Move auth tests
* Fix Mvc.ViewFeatures

* Remove dependencies from Components.csproj
* Move forms sources and tests
* Reference .Forms from .Web (needed unless we also have .Forms.Web)
* Rebase on #12936

* CR: Add Authorization namespace
* Update ref sources
* Add missing using
