iris: Demote all callers of iris_flush_and_dirty_for_history() to iris_dirty_for_history().

The unconditional flushing performed by
iris_flush_and_dirty_for_history() is now redundant with the memory
barriers introduced previously in this series, which should be in a
better position to determine from which domain the buffer will
actually be used in the future, and whether an additional flush or
invalidation is required or redundant with other PIPE_CONTROL commands
emitted elsewhere.
