cogl-defines.h: Add a COGL_HAS_X11 define

This will be defined in cogl-defines.h whenever Cogl is built using a
winsys that supports X11. This implies CoglTexturePixmapX11 will be
available.

To make this work the two separate cogl-defines.h.in files have been
merged into one. The configure script now makes a @COGL_DEFINES@
substitution variable which contains the #define lines to put in
rather than directly having them in the seperate files.
