[libgpiod][PATCH] bindings: python: generate wheels for CPython 3.14

[Vincent Fazio]

Update cibuildwheel to add support for generating 3.14 wheels.

Configuration options for cibuildwheel have been moved to pyproject.toml
to keep it in line with other tools used by the bindings.

The configuration has been updated to skip generating free-threaded
wheels since the bindings do not support free-threaded builds [0] and
cibuildwheel generates them by default starting with CPython3.14 [1].

Closes: https://github.com/brgl/libgpiod/issues/138
Signed-off-by: Vincent Fazio <vfazio@gmail.com>
---
Testing was performed on CPython 3.14.0-rc2 for manylinux wheels and rc3
for musllinux wheels. Some test evidence is in the closing issue [0].
