of the one from the Python 3.9 branch, which dropped support for Windows

* [python3] Add vcpkg's include directories to the end rather than to the beginning.
This is safe because vcpkg never hydrates python3's $(PySrcDir)\externals directory, so it wasn't using vendored dependencies at all.
* [antlr4] Install antlr headers in antlr4-runtime rather than the root to avoid stomping on common name token.h.
This is consistent with the ubuntu packages.
