[Templating] Razor class library for components (#7461)

* [Components] Razor class library for components
* Updates the Razor Class Library to be a portable components library by
  default.
* Adds an option to support the old RCL that includes support for Views
  and pages.
* Usage:
  * `dotnet new razorclasslib` produces the same traditional Razor Class Library.
  * `dotnet new razorclasslib -s false` produces a Razor Class Library without views and pages support.
