248758d7 - Expose qnnpack's maxpool when going through aten::max_pool2d (#38896)

Expose qnnpack's maxpool when going through aten::max_pool2d (#38896) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/38896 Current way of exposing qnnpack's maxpool2d only works if max_pool2d op is quantized::max_pool2d. This diff moves the function about to expose it via aten::max_pool2d when dispatch key is QuantizedCPU. Test Plan: Quantized tests.
