The inaccuracy was caused by ONNX round requires nearest integer rounding for halway (0.5) cases.
std::round rounds away from zero, thus giving wrong results with halfway cases.
Replaced std::round with std::nearbyint which uses the correct rounding by default.

Fixes an issue that comes up for variable input slice with steps set manually in ONNX to default 1's.

Simplifies dimensions_of instructions to a literal when possible.
Intended to be used after the split_single_dyn_dim pass.

Since opset version 18, the Split operator allows splitting into unevenly sized outputs when the split input is not present, and a num_outputs attribute has been introduced.

responses to some PR comments, new parsing tests, and removed an IF block that blocked a needed check

comment cleanup, some test fixes, minor refactoring of parse_resize.  onnx_test still fails; needs to be updated with new instructions.

 Add tracing to benchmark to show which kernels are running and the time of every kernel
