    drm/xe: Implement VM snapshot support for BO's and userptr
    
    Since we cannot immediately capture the BO's and userptr, perform it in
    2 stages. The immediate stage takes a reference to each BO and userptr,
    while a delayed worker captures the contents and then frees the
    reference.
    
    This is required because in signaling context, no locks can be taken, no
    memory can be allocated, and no waits on userspace can be performed.
    
    With the delayed worker, all of this can be performed very easily,
    without having to resort to hacks.
