Straighten out 'realize' handling for ClutterGLXTexturePixmap

Browse Source 
Setting the pixmap for an unrealized ClutterGLXTexturePixmap should
not cause it to be realized, and certainly shouldn't cause the the
REALIZED flag to be set without using clutter_actor_realize().

This patch uses the simple approach that;

 - pixmap changes on an unrealized ClutterGLXTexturePixmap
   are ignored
 - when the ClutterGLXTexturePixmap is realized, we then create
   the GLXPixmap and the corresponding texture.

The call to clutter_glx_texture_pixmap_update_area() is moved
from create_cogl_texture() to
clutter_glx_texture_pixmap_create_glx_pixmap() since
create_cogl_texture() is only called from one place, and updating
the area is really something we do *after* creating the texture,
not part of creating the texture.

clutter_glx_texture_pixmap_create_glx_pixmap() is reorganized a
bit to avoid debug-logging confusingly if it's called before a pixmap
has been set, and for readability.
