Subject: [PATCH] swig: use the Python 3 C API instead of the removed PyInt_*
 aliases (#1878)

src/libratbag.i calls PyInt_Check(), PyInt_AsLong() and PyInt_FromLong().
Those are Python 2 functions; they only ever worked because SWIG emitted
compatibility macros mapping them onto their PyLong_* counterparts in the
generated wrapper. SWIG 4.5.0 dropped those macros, so the generated
libratbag.c no longer compiles:

  libratbag.c: In function '_wrap_ratbag_device_get_vendor_id':
  libratbag.c:4583:17: error: implicit declaration of function
    'PyInt_FromLong'; did you mean 'PyLong_FromLong'?
  libratbag.c:4583:15: error: assignment to 'PyObject *' from 'int' makes
    pointer from integer without a cast [-Wint-conversion]

Call the PyLong_* functions directly. The bindings are generated with
swig -py3, so there is no Python 2 build to keep working, and the macros
they replace expanded to exactly these functions.

Built and verified on Arch Linux with swig 4.5.0, Python 3.14, meson 1.12.0, gcc 15: `_libratbag.so` and `_hidpp.so` link cleanly with the change and fail without it.
