Custom logger for onnx runtime

[nbigaouette]

Use CreateEnvWithCustomLogger() instead of CreateEnv() when creating environment as to pass a custom logger.

This allows logging on the Rust side through the tracing crate.

NOTE: The logid is initially empty even though I was expecting it to always contain the environment name (Environment::builder().with_name("test")). At some point it starts to contain the proper environment name. Maybe a bug in the runtime?

For example:

[...]
Aug 26 21:56:29.624 DEBUG onnxruntime{category="onnxruntime" file="sequential_executor.cc" line_number="150" function="Execute" logid=""}: onnxruntime::onnxruntime: "Begin execution"
Aug 26 21:56:29.625 DEBUG onnxruntime{category="onnxruntime" file="bfc_arena.cc" line_number="263" function="AllocateRawInternal" logid="test"}: onnxruntime::onnxruntime: "Extending BFCArena for Cpu. bin_num:13 rounded_bytes:3154176"
[...]
