win32: Fixes 32 bits visual studio module definition files by add script gen_vs_module_defs.py

Getting opengl32*.def consistence with Windows SDK.
Getting osmesa.mingw.def's gl* functions consistence with Windows SDK.
stw_* functions are cdecl, not stdcall, so there is no need mangling the symbol.
Fixes egl.def for x86
d3d10sw: Move the place of d3d10_sw.def to d3d10_sw.def.in
Fixes vulkan_lvp.def for x86
Fixes #5552
Remove stdcall-fixup
