Update latest Python module code

Use Python 3.x readline.c from GitHub 3.13 branch (commit 417dd3a dated
2024-05-06, released as part of 3.13.0). Add corresponding Argument
Clinic header file, readline.c.h (commit be5e8a0 dated exactly a year
ago on 2023-10-17, also part of 3.13.0).

As a reminder, we currently patch the following in readline.c:
  - Rename module name in PyModuleDef struct: "readline" -> "gnureadline"
  - Rename function: PyInit_readline -> PyInit_gnureadline
  - Add: #undef WITH_EDITLINE
  - Include "../../readline/readline.h" and not <readline/readline.h>
  - Include "../../readline/history.h" and not <readline/history.h>
