This commit consolidates DRM buffer management to the MetaDrmBuffer types, where the base type handles the common functionality (such as managing the framebuffer id using drmModeAdd*/RMFb()), and the sub types their corresponding type specific behavior. This means that drmModeAdd*/RmFB() handling is moved from meta-gpu-kms.c to meta-drm-buffer.c; dumb buffer allocation/management from meta-renderer-native.c.
