cogl/configure.ac: Adds --enable-stub-winsys option

Browse Source 
We want to be able to split Cogl out as a standalone project but there
are still some window systems that aren't natively supported by Cogl.
This allows Clutter to support those window systems directly but still
work with a standalone Cogl library.

This also ensures we set the SUPPORT_STUB conditional in clutter's
configure.ac when building for win32/osx and wayland.

dnl The "stub" winsys is a fallback option we use when Cogl doesn't
dnl yet have support for a window system. It enables a toolkit like
dnl Clutter to provide external support instead. Currently this is
dnl not compatible with other window system backends.
