MOD-11784 Align first batch size updateTriggerThreshold for non-compressed svs tiered index
In tiered SVS indexes, vector transfer to the backend SVS index is triggered as follows:
trainingTriggerThreshold, defaults to ~10k vectors (10 * block_size = 1024)updateTriggerThreshold, defaults to 1024 vectors (block_size)For non-compressed SVS indexes, the large initial batch provides no performance or accuracy benefit, and creates an inconsistent user experience compared to subsequent batches.
