* Change PlatformToolset to v143.
* Make e2e tests figure out the right Triplet to use on their own (previously, the vs-integration tests only passed given x86-windows so we may as well just lock it to that)
* Provide a default WorkingRoot in a reasonable place.
* Add CMake entries to the vcpkgTools.xml used in testing so that the tests pass if CMake is needed to extract a zip.
