Add a 'Green Hills MULTI' generator on Windows

Green Hills MULTI is an IDE for embedded real-time systems.  The IDE's
product page can be found here:

 http://www.ghs.com/products/MULTI_IDE.html

It supports cross compiling on ARM, Intel x86, and other architectures
with various operating systems.  The IDE exists on Linux and Windows
host systems, but CMake will currently only generate the project files
on Windows host systems.
