cogl-debug: Mark _cogl_debug_flags with dllexport for MSVC

Browse Source 
When building with MSVC, symbols to be exported that point to data
need to be marked with dllimport to be successfully imported. The
_cogl_debug_flags variable is currently exported because it is used
from cogl-pango. This patch adds a COGL_EXPORT macro to cogl-util.h
which is used in cogl-debug.h

Based on a patch by Chun-wei Fan
