* Create a new package - Microsoft.AspNetCore.App.Runtime.${rid} - which contains crossgen-ed versions of shared framework assemblies. This will be used by the SDK to replace rid-split packages
* Add a task which can generate the .deps.json file for the shared framework. Unlike the existing task we have, this does not rely on consuming a .deps.json file generated by first running a restore on packages.
* Move the reference to xunit.runner.console into the normal targets and files for managing dependencies
* Produce binlogs during build
Changes:
* Remove obsolete targets which are unnecessary now that this repo no longer builds git submodules in a separate build process
* Remove the need for static analysis of 'ArtifactInfo' items
* Simplify how the code signing task is configured
* Remove unused repo tasks
* Remove duplicate lists of external dependencies and packages to be produced
* Remove obsolete build definition
* Remove obsolete build script parameters
* Add VisualStudioSetupOutputPath
