Summary:
Added where logs are being added to constrain violations in draft export.
Example output:
```
1. Constraint violation error.
The specified input dynamic_shapes spec was found to be incorrect during tracing.
Specifically, this guard was added: Eq(s0, 3), where {'s0': "L['args'][0][0].size()[0]"}.
This occured at the following stacktrace:
File /data/users/angelayi/fbsource/buck-out/v2/gen/fbcode/1beb9df83fd74b9a/scripts/angelayi/draft_export/__test_draft_export__/test_draft_export#link-tree/torch/nn/modules/module.py, lineno 1736, in _wrapped_call_impl

File /data/users/angelayi/fbsource/buck-out/v2/gen/fbcode/1beb9df83fd74b9a/scripts/angelayi/draft_export/__test_draft_export__/test_draft_export#link-tree/scripts/angelayi/draft_export/test_draft_export.py, lineno 138, in forward.
Because of this, we have modified the dynamic shapes structure to be the following:
```
dynamic_shapes = {'a': {0: 3}}
```
```
The result of this diff is also that `dynamic` logs are permanently turned on during draft export. Otherwise we cannot capture the `[guard added]` logs from symbolic_shapes.py.
Test Plan: `buck2 run @//mode/dev-nosan scripts/angelayi/draft_export:test_draft_export -- -r "test_shape_failure" `

# Top level logging module for torch logging

# Simple setup for onboarding (see above doc for more detail):
|
|
# 1. register any top-level log qualified name for your module in torch._logging._registrations (see there for examples)
|
|
# 2. register any artifacts (<artifact_name> below) in torch._logging._registrations
|
|
# a. call getArtifactLogger(__name__, <artifact_name>) at your logging site instead of the standard logger to log your artifact
