Add support for GLFW_NATIVE_INCLUDE_NONE macro

Browse Source 
By default, the glfw3native.h header will include the platform-specific
headers necessary for the return types of GLFW native access functions.

Sometimes it is preferrable to declare those types

This commit adds support for the GLFW_NATIVE_INCLUDE_NONE macro, which
when defined disables the inclusion of all platform-specific headers.

Fixes #1348
