Qwen3 VLM: handle scenario specifc latency setting and dataset sample count to submission checker

[zihaok]

Background:
Qwen3 Offline and Server scenario uses 48289 samples, but Interactive scenario use 8000 samples due to runtime cost.

Hence, the difference between Server and Interactive scenario are

• Latency constraint: 12s vs 1.5s
• dataset sample count: 48289 vs 8000
• Accuracy threshold: 0.7903 * 0.99 vs 0.78777 * 0.99

This PR adds this logic in submission checker to address these two scenario differences in Qwen3.
