gallium: Reorg texture usage flags

Introduce a new shared usage and rename primary to scanout.
The display target usage is more of a windows concept and
doesn't mean the same thing as shared. Display target means
that the surface should be presentable, for softpipe this
means that it should be backed by a hardware buffer.
