Walk transparent ops when extracting input quant params (#20139)

[ethansfng]

Summary:

SAM 3's encoder input feeds a transparent shape op first — placeholder → reshape (patchify) → quantize_per_tensor — whereas the original code only recognized placeholder → quantize_per_tensor (a quantize directly on the input). The change walks through transparent ops (reshape/permute/transpose/etc.) from the input to reach the first quantize, so that indirected pattern resolves.
