Publish minified .js files as a package, remove related components from Shared Framework

[wtgodbe]

We should pull the minified .js files & their related components out of the Shared Framework, and instead distribute them as an out-of-band runtime pack that will be available in the Visual Studio offline package cache - this is what the WebAssembly SDK already does for their JS components, and should make it much easier to build aspnetcore as part of offline source-build in the VMR. CC @javiercn in case I'm missing any details.

Blazor is great but it needs to be more object oriented and there are a lot of Un-logical issues in control event handling that should be solved

@javiercn can this be closed now?
