st/dri: support format modifier queries
ask the driver for supported modifiers for a given format.
v2: move to __DRIimageExtension v16.
v3: fail if the supplied format is not supported by driver.
v4: purge PIPE_CAP_QUERY_DMABUF_ATTRIBS.
v5:
- move to __DRIimageExtension v15, pass external_only to the driver.
