[ONNX] Export node and value with scope name (#82040)
Introduce `_jit_pass_onnx_assign_node_and_value_names` to parse and assign
scoped name for nodes and values in exported onnx graph.
Module layer information is obtained from `ONNXScopeName` captured in `scope`
attribute in nodes. For nodes, the processed onnx node name are stored in
attribute `onnx_name`. For values, the processed onnx output name are stored
as `debugName`.
