[dynamo][profiler] More verbose profiler warning (#105362)
torch.profiler.record_function and torch.profiler.profile are ignored by dynamo. In the common case, users have `record_function` in the middle of their program in order to annotate a section of the profile.
The previous error message was `Profiler will be ignored`. Users would think that profiling would be completely ignored.
Now the message will look like `Profiler function <class 'torch.autograd.profiler.record_function'> will be ignored`.
