py-pytype: updated to 2024.9.13

Version 2024.09.13:

Updates:
* Basic support for Python 3.12.

  With this release you can run pytype with Python 3.12. But pytype has no
  support for any new features added in Python 3.12.

  Look out for type checking changes caused by different bytecode emit:
  * dict/list/set comprehensions are type checked 1 level deeper.
  * Errors after `if` statements can be printed differently.

* Add support for pickled pyi files in merge_pyi.py.

* Several performance improvements.

* Stop validating imports map. Pytype used to validate that each file in an
  import map exists. This has proved too costly, especially on network file
  systems. Pytype now assumes import maps specified via --imports_info are
  correct.

* Add support for flag files (required for Bazel workers).

* Change the format of errors printed to the console.

  Errors now also include the column number and a code snippet, which highlights
  the part that's broken.

  Old:
    File "test.py", line 4, in foo: unsupported operand type(s) for +: \ 
str and int [unsupported-operands]
      Function __add__ on str expects str
  New:
    test.py:4:10: error: in foo: unsupported operand type(s) for +: str and int \ 
[unsupported-operands]
      Function __add__ on str expects str
        print(arg + 3)
              ~~~~~~~

Bug fixes:
* Add type definitions for `aiter()` and `anext()`.
* Don't include deleted top-level variables in module types.
* Don't crash when a Generic subtype uses a TypeVar differently.
* Fix type inference for `iter(func, None)`.
