...For both the regular WGL winsys and SDL winsys builds, that
COGL_HAS_GTYPE_SUPPORT is defined, so that the builds won't break as
Visual Studio builds do assume an existing installation of GLib.

-Create a pre-defined cogl/cogl-gl-header.h(.win32) that is to be used on
any Windows builds, and adapt the MSVC build process to set up and use
that file.
-Fix up glib-mkenums code generation .bat file that is generated during
"make"/"make dist", like the autotools-based builds.
-Since cogl/cogl-defines.h now contain versionioning info, and it no longer
directly includes the GL headers, update the pre-configured
cogl-defines.h[.win32|.win32_SDL] and use autotools to fill in the
versioning info during "make"/"make dist".
-Fix up cogl/cogl-pango.rc.in so that they reflect the cogl-2.x versioning
stuff correctly and versioning info can be filled in correctly during
"make"/"make dist"
