sw_winsys: Add winsys_handle to displaytarget_create_mapped

Browse source 
The main intention is to allow to pass dmabuf handles, however as its
type differs depending on platform, just pass the whole whandle.

Also make use of it in llvmpipe_resource_from_handle(), in preparation
for the next commit.
