Implements Component code generation and tooling support end to end
udditionally adds some default `@addTagHelper` directives to make

during the build/IDE process. This drives the code generation during
build and lights up a bunch of editor features.
Add
Adds a little more use of Razor extensibility.
Razor is a plugin model, so we can't be the 'first mover' for initiating
compilation in the build tools and IDE.
Reorganizes tests and fills out more reusable test infrastructure for
Razor-driven testing.
Adds tests for declaration-only configuration.
