Move CoreCLR to the modern build tools and dnx

This changes moves coreclr onto DNX (same version as corefx).  Theoretically, this should allow these tests to target the desktop CLR.  All of the old package.config files are gone and replaced with corresponding project.json files.  The up front restore behavior is retained.  Tests are now buildable individually, though not runnable in a similar fashion.
