[TorchTidy] Add pattern to detect if bias is enabled in conv2d followed by batchnorm2d (#81941)
Summary: For cuda models only, if we have nn.Conv2d followed by nn.Batchnorm2d, we don't actually need to use bias=True in Conv2d as the math will cancel out the effect of bias
Test Plan: Added test in test_profiler.py
