Summary:
Context: https://github.com/pytorch/pytorch/pull/53299#discussion_r587882857
These are the only hand-written parts of this diff:
- the addition to `.github/workflows/lint.yml`
- the file endings changed in these four files (to appease FB-internal land-blocking lints):
- `GLOSSARY.md`
- `aten/src/ATen/core/op_registration/README.md`
- `scripts/README.md`
- `torch/csrc/jit/codegen/fuser/README.md`
The rest was generated by running this command (on macOS):
```
git grep -I -l ' $' -- . ':(exclude)**/contrib/**' ':(exclude)third_party' | xargs gsed -i 's/ *$//'
```
I looked over the auto-generated changes and didn't see anything that looked problematic.

Summary:
Update the API to access grad in cpp to avoid unexpected thread safety issues.
In particular, with the current API, a check like `t.grad().defined()` is not thread safe.
- This introduces `t.mutable_grad()` that should be used when getting a mutable version of the saved gradient. This function is **not** thread safe.
- The `Tensor& grad()` API is now removed. We could not do a deprecation cycle as most of our call side use non-const Tensors that use the non-const overload. This would lead to most calls hitting the warning. This would be too verbose for all the users.

Summary:
Fixes https://github.com/pytorch/pytorch/issues/38716, fixes https://github.com/pytorch/pytorch/issues/37234
This algorithm does the summation along a single axis with multiple "levels" of accumulator, each of which is designed to hold the sum of an order of magnitude more values than the previous.
e.g. if there are 2^16 elements, the first level will hold the sum of 2^4 elements, and so on in increasing powers of 2: 2^4, 2^8, 2^12 and finally 2^16.
This limits the differences in magnitude of the partial results being added together, and so we don't lose accuracy as the axis length increases.
WIP to write a vectorized version.

Summary:
The original design of `torch::nn::utils::clip_grad_norm_` / `clip_grad_value_` takes input by non-const reference, which prevents users from passing rvalue reference as input into the functions. This PR changes the functions to take input by value, which matches the Python version's semantics, and also adheres to the C++ API convention that if a function modifies its input in-place, it should take that input by value.

Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/26140
Per https://github.com/pytorch/pytorch/issues/25883, we want to work
towards C++/Python API parity. This diff adds clip_grad_norm_ to the c++ API to
improve parity.
