Adds the @page directive and support for specifying routes in components
at compile time.
For now the route is required and must begin with a leading /.
This removes a limitation that prevented callers from passing
attributes to a component that aren't backed by properties.
The majority of the complication here is required to deal with the more
sophisticated way that HTML attributes are represented in the Razor IR.
This builds upon existing support for UIEventHandler-typed component
properties and applies the same principle to any delegate type.
We try to help by generating the LSH of the lambda `=>` allowing you to
write `OnClick="Foo()"` rather than `OnClick="(e) => Foo()"`. You can of
course use @ as an escape.
The only rough edge here is that if the parameter names aren't memorable
for the delgate type, it's not super helpful.
Implements Component code generation and tooling support end to end
udditionally adds some default `@addTagHelper` directives to make
programming in Blazor a little nicer.
Components are discovered as Tag Helpers using Razor's extensibility
during the build/IDE process. This drives the code generation during
build and lights up a bunch of editor features.
