d85627ae - [CPU] Use MayInPlace kernel def hint for FusedConv kernel (#26422)

[CPU] Use MayInPlace kernel def hint for FusedConv kernel (#26422) ### Description Use MayInPlace hint for the FusedConv NCHW CPU kernel that allows for the allocation planner to re-use the optional "sum" input buffer as the kernel's output buffer. It will potentially save [this copy](https://github.com/microsoft/onnxruntime/blob/06004826cc99dd8b8b92dbf000db3d3525716f22/onnxruntime/core/providers/cpu/nn/conv.cc#L209) if the buffers can be shared (in most cases the buffers can be shared) ### Motivation and Context The kernel already had logic to save the copy but the kernel def was missing the hint to the allocation planner. Found while investigating improvements to a Conv model's performance on ARM64
