* gh-140550: PEP 793 reference documentation
Since the PEP calls for soft-deprecation of the existing initialization
function, this reorganizes the relevant docs to put the new way of
doing things first, and de-emphasize the old.
Some bits, like the tutorial, are left out of this patch. (See the
issue for a list.)

* Docs: Move Enum functions and add examples
When the `Enum` functions `_add_alias_` and `_add_value_alias_` were added in de6bca9564, the documentation for them was done under `EnumType` instead of `Enum`.
This change moves them to the docs of the `Enum` class and adds an example for each function.

The documentation incorrectly stated that generator.close() 'raises' a
GeneratorExit exception. This was misleading because the method doesn't
raise the exception to the caller - it sends the exception internally
to the generator and returns None.
Some curses module-level functions and window methods now raise
a `curses.error` when a call to a C curses function fails:
- Module-level functions: assume_default_colors, baudrate, cbreak,
echo, longname, initscr, nl, raw, termattrs, termname, and unctrl.
- Window methods: addch, addnstr, addstr, border, box, chgat,
getbkgd, inch, insstr, and insnstr.
In addition, `curses.window.refresh` and `curses.window.noutrefresh`
now raise a `TypeError` instead of a `curses.error` when called with an
incorrect number of arguments for pads.
See also ee36db5500 for similar
changes.
Extension builders must specify Py_GIL_DISABLED if they want to link to the free-threaded builds.
This was usually the case already, but this change guarantees it in all circumstances.
\Z was an error inherited from PCRE 0.95. It was fixed in PCRE 2.0.
In other engines, \Z means not “anchor at string end”, but
“anchor before optional newline at string end”.
\z means “anchor at string end” in most RE engines.
Add a developer-facing document describing the protocol used by
remote_exec(pid, script) to execute Python code in a running process.
This is intended to guide debugger and tool authors in reimplementing
the protocol.

Make `warnings.catch_warnings()` use a context variable for holding
the warning filtering state if the `sys.flags.context_aware_warnings`
flag is set to true. This makes using the context manager thread-safe in
multi-threaded programs.
Add the `sys.flags.thread_inherit_context` flag. If true, starting a new
thread with `threading.Thread` will use a copy of the context
from the caller of `Thread.start()`.
Both these flags are set to true by default for the free-threaded build
and false for the default build.
Move the Python implementation of warnings.py into _py_warnings.py.
Make _contextvars a builtin module.
