This refactors the targets used to build the shared framework and its .zip files. There are lots of reasons motivating this: Arcade convergence, migration to VSTS, making it easier to build this locally, etc.
Changes:
* Moves move content of build/Sharedfx.{props/targets} into eng/targets/SharedFx.Common.{props/targets}
* Update the build to produce a `runtime.$rid.Microsoft.AspNetCore.App` package (not just the one with symbols in it)
* Refactor the targets which produce .tar.gz/.zip files into separate projects in `src/Installers/`
* Refactor installers, unit tests, and the framework projects to use ProjectReference to flow dependencies between different parts of the build.
* Makes it easier to build the shared framework locally (for the inner dev loop, you can run `dotnet build -p src/Framework/Microsoft.AspNetCore.App/src/ -r win-x64`)
As a part of converging repos, we no longer need this code. It is currently buggy and slow, and we can get away without by hard-coding the repo graph (which rarely changes)
List explicitly as .csproj files the scenarios for which the offline package cache is important
Produces new artifacts designed for various scenarios, such as:
* Docker (where xml doc files are not needed)
* Azure web apps (where 1.x SDKs must still be supported, but xml docs are not needed)
