New additions to the tty library. Functions added: cfmakeraw(), and cfmakecbreak(). The
functions setcbreak() and setraw() now return original termios to save an extra tcgetattr() call.

This threw a SystemError before #104603. Adding a separate test
because this was a different failure mode than the other two new
tests from #104603, both of which used to segfault.
This adds a number of PRIO_DARWIN_* constants to the os module for use with os.setpriority.

Annotate the following:
- methods of class Class
- methods of class Module
- methods of class PythonParser
- function compute_checksum()
- function parse_file()
- global variable unsupported_special_methods
- Convert `unspecified` and `unknown` to be members of a `Sentinels` enum, rather than instances of bespoke classes.
- An enum feels more idiomatic here, and works better with type checkers.
- Convert some `==` and `!=` checks for these values to identity checks, which are more idiomatic with sentinels.
- _Don't_ do the same for `Null`, as this needs to be a distinct type due to its usage in `clinic.py`.
- Use `object` as the annotation for `default` across `clinic.py`. `default` can be literally any object, so `object` is the correct annotation here.

Introduce TypeSet, and use it to annotate the 'accept' keyword of
various C converters. Also add some missing return annotations for
converter init functions.
Move all of the Python C API calls into the parent process up front
instead of doing PyLong_AsLong and PyErr_Occurred and PyTuple_GET from
the post-fork/vfork child process.
Much of this was long overdue. We shouldn't have been using PyTuple and
PyLong APIs within all of these low level functions anyways.
During the PEP 695 implementation at one point I made
TypeVar.__name__ return garbage, and all of test_typing passed.
So I decided to add a few more tests. In the process I discovered
a minor incompatibility from the C implementation of TypeVar:
empty constraints were returned as None instead of an empty tuple.
This fixes several ways file descriptors could be leaked from `subprocess.Popen` constructor during error conditions by opening them later and using a context manager "fds to close" registration scheme to ensure they get closed before returning.
