This PR bumps FlashInfer and updates PagedKVCache accordingly for performance improvement. Some notes on this bump: * When the Grouped-Query Attention group size is at least 4 and FlashInfer is enabled, we use the prefill attn kernel for better performance. * We enlarge the temporary workspace for FlashInfer use accordingly, as FlashInfer in the current version may consume much larger workspace. We turn off the workspace when FlashInfer is not enabled. * We reduce the max block depth to be 2, in observation of the limited help of cascade inference when batch size is not large and the prompt reuse is low.
