stijn d96391aca3 mpy-cross,windows: Add msvc build of mpy-cross.
Add the project file to the mpy-cross directory, which is also where the
executable ends up, and change the Appveyor settings to build mpy-cross
with both msvc and mingw-w64 and verify this all works by running tests
with --via-mpy.

MicroPython cross compiler

This directory contains the MicroPython cross compiler, which runs under any Unix-like system and compiles .py scripts into .mpy files.

Build it as usual:

$ make

The compiler is called mpy-cross. Invoke it as:

$ ./mpy-cross foo.py

This will create a file foo.mpy which can then be copied to a place accessible by the target MicroPython runtime (eg onto a pyboard's filesystem), and then imported like any other Python module using import foo.

Different target runtimes may require a different format of the compiled bytecode, and such options can be passed to the cross compiler. For example, the unix port of MicroPython requires the following:

$ ./mpy-cross -mcache-lookup-bc foo.py

Run ./mpy-cross -h to get a full list of options.
