### FP16 optimizer automatically detect DeepSpeed compatibility
Optimum/Transformers are using accelerate lib to prepare models, so our
FP16 optimizer wrapper does not work for long time. Because the
namespace is `accelerate.utils.deepspeed.DeepSpeedOptimizerWrapper`,
which underlying is still calling into DeepSpeed stage1and2 optimizer.
This PR includes following changes:
1. Add `accelerate.utils.deepspeed.DeepSpeedOptimizerWrapper` in the
modifier registry, plus a check on its contained `optimizer` property
MUST be DeepSpeed stage 1 and 2 optimizer. (let's cover Stage 3
optimizer later)
2. For DeepSpeed version > 0.9.1, we will store the source code in a
version list. As long as the related function in DeepSpeed remains
unchanged during its new release, we won't need manually upgrade the
version check any more. If some day, the source code did not match, a
warning will be raised to users, to add a new version of source code in
the list.
With the above change, we will have our FP16 Optimizer working again in
Optimum.
### Description
`lintrunner` is a linter runner successfully used by pytorch, onnx and
onnx-script. It provides a uniform experience running linters locally
and in CI. It supports all major dev systems: Windows, Linux and MacOs.
The checks are enforced by the `Python format` workflow.
This PR adopts `lintrunner` to onnxruntime and fixed ~2000 flake8 errors
in Python code. `lintrunner` now runs all required python lints
including `ruff`(replacing `flake8`), `black` and `isort`. Future lints
like `clang-format` can be added.
Most errors are auto-fixed by `ruff` and the fixes should be considered
robust.
Lints that are more complicated to fix are applied `# noqa` for now and
should be fixed in follow up PRs.
### Notable changes
1. This PR **removed some suboptimal patterns**:
- `not xxx in` -> `xxx not in` membership checks
- bare excepts (`except:` -> `except Exception`)
- unused imports
The follow up PR will remove:
- `import *`
- mutable values as default in function definitions (`def func(a=[])`)
- more unused imports
- unused local variables
2. Use `ruff` to replace `flake8`. `ruff` is much (40x) faster than
flake8 and is more robust. We are using it successfully in onnx and
onnx-script. It also supports auto-fixing many flake8 errors.
3. Removed the legacy flake8 ci flow and updated docs.
4. The added workflow supports SARIF code scanning reports on github,
example snapshot:
5. Removed `onnxruntime-python-checks-ci-pipeline` as redundant

#11315, #11316
* optimize python overhead of _post_amp_backward
* overwrite apex amp's zero_grad for faster implementation
* move unscale_fp16_grads_into_fp32_grads into C++ impl
* improve the efficiency furthur, reducing 3.5ms to 1.7ms for unilm.
* unilm 1.7ms to 338us: 1). optimize python list <==> std::vector copy, 2). launch the kernels as long as num_elem reach thresh hold. This help reduce the CUDA idel time.
* refine the logic a bit after validating
