gallium/radeon: add RADEON_FLAG_HANDLE
When passed to winsys->buffer_create, this flag will indicate that we require a buffer that maps 1:1 with a kernel buffer handle. This is currently set for all textures, since textures can potentially be exported to other processes. This is not a huge loss, since the main purpose of this patch series is to deal with applications that allocate many small buffers. A hypothetical application with tons of tiny textures might still benefit from not setting this flag, but that's not a use case I'm worried about just now.
