Win32: Update predefined cogl-defines.h's

-Add a define for COGL_HAS_GLIB_SUPPORT, the Visual C++ projects will build
 GLib support for COGL for all builds at this time, unless there is a
 significant call for the need of a COGL Visual C++ build with no
 dependency on GLib
-Pre-define COGL_SYSDEF_POLL* as listed in the default values in commit
 74974752 since Windows does not have poll.h and thus does not have special
 values for these.
