Fix DropQDQ not dropping Q/DQ around opset-22 MaxPool (#29201)
### Description
ONNX added a `MaxPool-22` schema, but the DropQDQ selectors still
matched only `MaxPool-12`, so the `DequantizeLinear` / `QuantizeLinear`
around an opset-22 `MaxPool` were no longer dropped. This updates both
DropQDQ selector op-version maps to `{12, 22}`, matching the QDQ
propagation pass. (`MaxPool` stays pinned to integer-capable versions ≥
12.)
### Motivation and Context
Fixes #28770. Models that optimized to full integer at opset ≤ 21
regressed at opset 22+, blocking users from upgrading their opset.
