Drop QDQ around more nodes #21376

With matching quantization parameters: DequantizeLinear ∘ Flatten ∘ QuantizeLinear is equivalent to just the Flatten, and it saves some floating- point computations. There's already support for a similar optimization for an equivalent Reshape: this change extends the existing optimization to also recognize Flatten. microsoft#21167
Currently, the DropQDQNodesRules optimization removes QuantizeLinear and DequantizeLinear nodes from DequantizeLinear∘MaxPool∘QuantizeLinear. However, if the x_scale/y_scale values are non-positive, this changes the ordering of the elements in the input value, so this optimization is changing the results. This change adds a check for whether the scale in the QuantizeLinear (or DequantizeLinear) is a positive scalar, and a new selector to disallow removing the QDQ around MaxPool if it is not. microsoft#21176
Only does so if the scale is positive
No integer implementations are present, so they need to stay in floating-point. microsoft#21287
Don't expect the drop qdq optimization to work for multiple inputs for now.
Apparently the type constraints for these ops don't include 16-bit integers.
Results don't appear to match

Changes are on top of #21182, since it also needs to check for positive scale when dropping QDQ around ReduceMin and ReduceMax |

I guess these are no longer lined up anyway after moving some to previous line.

I had missed the reason why the windows builds were failing last few commits (currently don't have a Windows system to try locally), sorry I guess since it's I'll try adding the onnxruntime/cmake/onnxruntime_unittests.cmake Line 892 in b9f3a5d |
Seeing: fatal error C1128: number of sections exceeded object file format limit: compile with /bigobj so apparently these additional tests are pushing this file over the limit. Given there's already a statement setting /bigobj for sibling graph_transform_test, simply copy-pasting that for qdq_transformer_test

Description
Extends the Drop QDQ optimization to remove DequantizeLinear and QuantizeLinear nodes from around operators:
Motivation and Context
To reduce floating-point conversions in quantize inference. Mainly motivated by the Flatten case, since that will show up in graphs exported from PyTorch to ONNX. But to make the change complete, extending to a larger set of ops for which this optimization is valid.
