Adjust cpp torch trt logging level with compiler option

[keehyuna]

Description

Log level of python and native TRT logger is set differently. Same level from compiler option should be helpful to work with development version of torch-TRT module.

• python trt logger: when compiler option provide debug=True
• c++ trt logger: compiled at build time

TorchTRTLogger.cpp
#ifndef NDEBUG
static TorchTRTLogger global_logger("[Torch-TensorRT - Debug Build] - ", LogLevel::kDEBUG, true);
#else
static TorchTRTLogger global_logger("[Torch-TensorRT] - ", LogLevel::kWARNING, false);
#endif

And profile option for c++ trt runtime module is enabled by debug level logging. This is helpful to measure/evaluate
performance with development version of torch-TRT module

What happens in the case that it is a python only build? You might want to use enabled features to gate access to this code to only when the C++ runtime is available.

You're right, I see the problem. Updated the change.
