Fix APIENTRY from windows.h being undefined

Browse Source 
Some extension loader headers include windows.h.  If they were included
before glfw3.h, glfw3native.h would leave APIENTRY undefined.  This adds
the GLFW_APIENTRY_DEFINED macro to signal when GLFW "owns" APIENTRY and
may undefine it.

Fixes #1062.
