Include SyncLane in includesBlockingLane helper (#34543)

This helper weirdly doesn't include the sync lane.

Everywhere we use it we have to check the sync lane separately. We can
simplify things by simply including the sync lane.

This fixes a lack of optimization because we should not check the store
consistency for a `flushSync` render.
