Create new 'runtime pack' nuget packages for Microsoft.AspNetCore.App (#7475)

* 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
