In the process, also fix the make-torque-parser.py script to work in its new
location.

This CL creates the "tools/torque" directory. It moves the existing
two scripts (making the parser and formatting Torque code) into that
director.

The extension lives in "tools/torque/vscode-torque" and currently only
provides basic syntax highlighting support. The easiest way to
install the extension is to simply create a symlink into your local
vscode extension directory (see README.md).
