https://github.com/pytorch/pytorch/pull/152708 expanded support of `get_estimated_runtime` to many more types of `SchedulerNodes`. This caused an increase in compile time because we're always calling `get_estimated_runtime` to populate the metrics table. This PR adds a flag for this logging, which reduces the instruction count by 8%. Long term, we should probably merge metrics.py with TORCH_LOGS/tlparse (suggestion from @xmfan).
Update: added support for TORCH_LOGS for the metrics logging.
Test Plan:
mm_loop.py and many existing tests cover.

User defined NN module might have their own `__len__` or `__bool__`
methods which Dynamo needs to trace through, so that side effects and/or
reads to buffered writes are properly handled.
This patch removes the special `UnspecializedNNModuleVariable` branch in
Dynamo's branch handling, and lets these cases fall into the
`UserDefinedObjectVariable` branch, which handles the aforementioned
cases correctly.
Fixes#145284.

In hinsight, we never needed a DICT_SUBCLASS_GUARD_MANAGER, because Dynamo would inline through the overridden keys method. In this PR, we ensure that while creating guards and constructing variable trackers, we get the `d.keys()` value by using `dict.keys(d)`. This ensures that we do not call overridden keys method. Therefore, the C++ guard can use `PyDict_Next` directly to check the guards.

Changes:
1. Bump `ruff` from 0.7.4 to 0.8.4
2. Change `%`-formatted strings to f-string
3. Change arguments with the `__`-prefix to positional-only arguments with the `/` separator in function signature.

This is a bug on the main exposed by https://github.com/pytorch/pytorch/issues/139476
We have dict tag optimization where if the dict tag does not change, we
skip guards on all the items of the dict that are "immutable". We
considered tensors as immutable in such scenarios. This is critical for
guard eval performance, because generally users dont change their
parameters.
If I try to remove this optimization, we see slowdowns, e.g, 3.03x to
2.95x on conv_mixer TIMM benchamrk.
So, I am adding a flag which keeps the current state but allows the
users to remove this optimization. Not ideal, but given how serious guard eval perf has to be,
we are in the gray are of unsoundness vs performance tradeoff.

This patch
- removes the `is_lazy_module` check from `is_dynamic_nn_module`, and
adds a regression test.
- removes a series of dynamo expected failures on lazy modules. The few
ones I checked all were failing due to speculation log divergence,
similar to #138489.
Note that #100047 introduced the conditional removed in this patch, and
it was trying to fix#100001. But I've confirmed locally that #100001 no
longer repros after this patch.
Fixes#138489. See more context in the issue.

Add similar semantics for creating a buffer object similar to creating a parameter. This is done by introducing a new Buffer class that can be used for type disambiguation. The underlying functionality of registering a buffer remains the same as the register_buffer method has not been changed. The persistent parameter in the Buffer type is to indicate whether a buffer object should be persistent or not. Other non-test changes have to do with getting the new Buffer type recognized by inductor and dynamo. Remaining changes are test changes to make sure that the Buffer type can be used as a drop in replacement for register_buffer as it just leads to register_buffer being called. The addition of this new functionality still allows for normal tensors to be used as buffers so these changes are intended to be backwards compatible.
Fixes#35735
