eab7dd49 - context manager/decorator for dynamo config patching during tracing (#150586)

context manager/decorator for dynamo config patching during tracing (#150586) Summary: Implement traceable config patching for Dynamo: enables restricted patching of Dynamo config where user can use a context manager/decorator to change tracing behavior for parts of the code. The new `dont_skip_tracing` decorator/context manager for ignoring most trace rules is easily implemented with this more generic traceable config patching feature. Implementation: - Create a new specialized context manager class representing a wrapper around torch._dynamo.config.patch - Dynamo doesn't trace into the context manager but updates config at compile time - Correctness is based on our correctness for handling supported context managers - Implementation is inspired by how `GradModeVariable` is implemented. Previous attempts: https://github.com/pytorch/pytorch/pull/148736 (decorator-only global approach) and https://github.com/pytorch/pytorch/pull/149439 (decorator-only traceback approach) See https://docs.google.com/document/d/1vWNwKL_jpg-PLopifcaSa338wks3GqSVF4GHRguybGg/edit?tab=t.0 for more details on implementation - including previous approaches. NOTE: this PR fixes a bug where skipped code objects were not tracked by convert_frame.py, leading to cases where code objects would be automatically skipped even after `torch._dynamo.reset()`. This exposed some latent dynamo-wrapped test failures in CI that previously passed in CI but not locally.
