Support clustering in saveAs..BigQueryTable

[dmateusp]

I am trying to write to a clustered table using saveAsTypedBigQueryTable and getting:

<table> is configured to use TableDestinationCoderV2. Set withClustering() on BigQueryIO.write() and,  if you provided a custom DynamicDestinations instance, override getDestinationCoder() to return TableDestinationCoderV3.

I only hit this when I am processing many partitions at once. I see that the SCIO API doesn't expose the withClustering option.
