Classfy glamor pixmap to different types.

Browse Source 
During the integration with intel driver, we introduce two
new type of pixmap, one is TEXTURE_DRM, the other is DRM_ONLY.
TEXTURE_DRM means we create a texture bind to the DRM buffer
successfully. And then the texture and the external BO is
consistent. DRM_ONLY means that we failed to create a texture
from the external DRM BO. We need to handle those different
types carefully, so we have to track them in the data structure.
