gallium: add PIPE_RESOURCE_PARAM_DISJOINT_PLANES

Browse source 
To query if a DRI_IMAGE has separate plane buffer handle.

radeonsi's DCC compressed dri image has multiple planes
(compressed data and metadata). But they share the same
buffer with different offsets, so we only need one buffer
handle for them.

This attribute is used to distinguish single buffer multi
plane image from multi buffer multi plane image.
