Remove some wildcards from mypy configs (#56645)
Summary:
See https://github.com/pytorch/pytorch/pull/56523#issuecomment-823562134 for context. Basically the idea is that people (including myself) keep assuming that the single-asterisk `*` wildcard means "match in this directory and in its subdirectories", which is _not_ true. Removing the wildcards thus reduces confusion.
Ideally I would like to remove _all_ of these wildcards and then add a lint to disallow them in the future (and also greatly simplify the pattern-matching logic in `tools/mypy_wrapper.py`; see https://github.com/pytorch/pytorch/issues/55702 for context), but currently this one can't be removed:
```
tools/autograd/*.py,
```
That is because there is a file called `tools/autograd/templates/annotated_fn_args.py` (added in https://github.com/pytorch/pytorch/issues/41575) which is not a valid Python file and thus cannot be checked by `mypy`. ezyang would it be possible to rename that file to use a suffix other than `.py`?
Pull Request resolved: https://github.com/pytorch/pytorch/pull/56645
Test Plan:
```
$ mypy
Success: no issues found in 1317 source files
$ mypy --config=mypy-strict.ini
Success: no issues found in 72 source files
```
The numbers of source files should be the same before and after this PR.
