SA: Dynamic input support — AMD NPU (VitisAI)

[DingmaomaoBJTU]

Overview

Extend static analyzer support for models with dynamic input shapes on AMD NPU (VitisAI EP). Complements static shape op coverage work in #145.

Scope

• Validate SA op classification for dynamic-shape models on AMD NPU (VitisAI EP)
• Target: ~520k test cases with dynamic input shapes

Acceptance Criteria

• SA correctly classifies ops for dynamic-shape models on AMD NPU (VitisAI EP)
• No regression in static shape coverage vs P1-EP-AMD-NPU-001: AMD NPU (Ryzen AI) — Op Coverage Collection #145 baseline
• Validated on 52w-scale dynamic input test cases
