Add methods __typing_subst__() in TypeVar and ParamSpec.
Simplify code by using more object-oriented approach, especially
the C code for types.GenericAlias and the Python code for
collections.abc.Callable.
GH-30297 removed a duplicate `from test import support` statement from `test_asyncio.test_sslproto`. However, in between that PR being filed and it being merged, GH-31275 removed the _other_ `from test import support` statement. This means that `support` is now undefined in `test_asyncio.test_sslproto`, causing the CI to fail on all platforms for all PRS.
Example:
async with asyncio.timeout(5):
await some_task()
Will interrupt the await and raise TimeoutError if some_task() takes longer than 5 seconds.

GH-26091 added the _typevar_types and _paramspec_tvars instance
variables to _GenericAlias. However, they were not propagated
consistently. This commit addresses the most prominent deficiency
identified in bpo-46581 (namely their absence from
_GenericAlias.copy_with), but there could be others.

- fd inheritance can't be modified because Emscripten doesn't support subprocesses anyway.
- setpriority always fails
- geteuid no longer causes problems with latest emsdk
- umask is a stub
- geteuid / getuid always return 0, but process cannot chown to random uid.
- getgroups always fails.
- geteuid and getegid always return 0 (root), which confuse tarfile and
tests.
- hardlinks (link, linkat) always fails.
- non-encodable file names are not supported by NODERAWFS layer.
- mark more tests with dependency on subprocess and multiprocessing.
Mocking does not work if the module fails to import.
This adds a new standard library module, `tomllib`, for parsing TOML.
The implementation is based on Tomli (https://github.com/hukkin/tomli).
## Steps taken (converting `tomli` to `tomllib`)
- Move everything in `tomli:src/tomli` to `Lib/tomllib`. Exclude `py.typed`.
- Remove `__version__ = ...` line from `Lib/tomllib/__init__.py`
- Move everything in `tomli:tests` to `Lib/test/test_tomllib`. Exclude the following test data dirs recursively:
- `tomli:tests/data/invalid/_external/`
- `tomli:tests/data/valid/_external/`
- Create `Lib/test/test_tomllib/__main__.py`:
```python
import unittest
from . import load_tests
unittest.main()
```
- Add the following to `Lib/test/test_tomllib/__init__.py`:
```python
import os
from test.support import load_package_tests
def load_tests(*args):
return load_package_tests(os.path.dirname(__file__), *args)
```
Also change `import tomli as tomllib` to `import tomllib`.
- In `cpython/Lib/tomllib/_parser.py` replace `__fp` with `fp` and `__s` with
`s`. Add the `/` to `load` and `loads` function signatures.
- Run `make regen-stdlib-module-names`
- Create `Doc/library/tomllib.rst` and reference it in `Doc/library/fileformats.rst`

This removes discrepancy between list["int"] and List["int"].

When an exception is created in a nested call to PyObject_GetAttr, any
external calls will override the context information of the
AttributeError that we have already placed in the most internal call.
This will cause the suggestions we create to nor work properly as the
attribute name and object that we will be using are the incorrect ones.
To avoid this, we need to check first if these attributes are already
set and bail out if that's the case.
