Block until this sink finishes flushing. Idempotent: `None` once it has nothing left to wait for.

With `timeout_ms`, gives up after that long and returns `False`,
leaving the sink flushing in the background for a later `wait()`.
This is how AXL drains build events after a cancel: the forwarders
get a bounded window to deliver bazel's `BuildFinished` before the
process exits. Returns `True` when the sink finished within the wait.
