drm/xe: Fix VM bind out-sync signaling ordering
A case existed where an out-sync of a later VM bind operation could
signal before a previous one if the later operation results in a NOP
(e.g. a unbind or prefetch to a VA range without any mappings). This
breaks the ordering rules, fix this. This patch also lays the groundwork
for users to pass in num_binds == 0 and out-syncs.
