gh-119118: Fix performance regression in tokenize module (#119615) 
* gh-119118: Fix performance regression in tokenize module

- Cache line object to avoid creating a Unicode object
  for all of the tokens in the same line.
- Speed up byte offset to column offset conversion by using the
  smallest buffer possible to measure the difference.

gh-117486: Improve behavior for user-defined AST subclasses (#118212) 
Now, such classes will no longer require changes in Python 3.13 in the normal case.
The test suite for robotframework passes with no DeprecationWarnings under this PR.

I also added a new DeprecationWarning for the case where `_field_types` exists
but is incomplete, since that seems likely to indicate a user mistake.

gh-116322: Add Py_mod_gil module slot (#116882) 
This PR adds the ability to enable the GIL if it was disabled at
interpreter startup, and modifies the multi-phase module initialization
path to enable the GIL when loading a module, unless that module's spec
includes a slot indicating it can run safely without the GIL.

PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went
with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148.

A warning will be issued up to once per interpreter for the first
GIL-using module that is loaded. If `-v` is given, a shorter message
will be printed to stderr every time a GIL-using module is loaded
(including the first one that issues a warning).
