Remove cosmo windows.h header.

extras/cosmopolitan/include/windows.h

-/*
-IMPORTANT NOTE: Cosmopolitan is not officially supported by miniaudio. This file was added just as
-a way to play around and experiment with Cosmopolitan as a proof of concept and to test the viability
-of supporting such a compiler. If you get compilation or runtime errors you're on your own.
-
----------------------------------------------------------------------------------------------------
-
-This is a version of windows.h for compiling with Cosmopolitan. It's not complete. It's intended to
-define some missing items from cosmopolitan.h. Hopefully as the project develops we can eventually
-eliminate all of the content in this file.
