Replace QEff einsum-based reduction workarounds with equivalent torch.sum()
forms now that ONNX subfunction ReduceSum axes are localized as constants.
Add a narrow ONNX transform that detects ReduceSum nodes inside FunctionProto
bodies where the axes input was promoted to a function formal input. When every
top-level call site passes the same compile-time integer constant for that
formal input, the transform inserts a local Constant node inside the function,
rewires ReduceSum to use it, removes the formal function input, and removes the
matching actual argument from each call site.
This keeps PyTorch code such as:
(query * query).sum(dim=-1, keepdim=True)
lowering to Mul + ReduceSum instead of requiring an einsum workaround, while
still presenting ReduceSum axes to the compiler as a compile-time constant
inside the ONNX FunctionProto.
