SDK updates for components tooling

This is a bug fix for the RazorComponentWithTargetPath xaml rule. We
need to have separate targets for components and views.

The other fix here is a change to the set of workarounds we're using for
components currently. We need this project capability for the correct
project host to be used when loading the project.
