[GDNative] added API struct wrapper generator

Browse Source 
Previously functions of the GDNative API were accessed by letting
the loader at load-time resolve the symbols. This causes troubles on
Windows (...sigh...), so now the GDNative API isn't exported anymore.

This means, that a library that wants to call a GDNative function
needs to access it via a struct of pointers that's passed to it at
right after the library was loaded. To make the usage easier, those
function pointers in the struct can be wrapped in actual function in
the global scope. This commit adds a generator for that wrapper code.
