[GDNative] Fix GDN_EXPORT define with mingw.

Browse source 
The define is **not used by godot**, but in GDNative libraries.

I'm not sure it should be defined there in the first place, though we
shouldn't change that (for compatibility).

This commit changes the platform detection order to detect mingw
compiling for windows (which defines `__GNUC__`).

This commit also wraps the definition around a guard to let libraries
override it with a build-time define.
