[BEAM-9675] BigQueryStorageStreamSource reader quota issues at split time

• Type: Bug

Description

The BigQuery Storage API returns an empty SplitStreamResponse when a stream cannot be split any further. The BigQueryStorageStreamSource reader should honor this response and not make further split calls for a stream when such a response is encountered; continuing to attempt splits leads to unnecessary quota exhaustion for management plane API calls.
