Add Python 3.12/3.13/3.14 support and fix Python 3.12 SyntaxWarnings

- cefpython_public_api.h: add PY_MINOR_VERSION cases for 3.12, 3.13, 3.14
- build.py: fix invalid escape sequences in regex strings (SyntaxWarning on 3.12+)
- cefpython3.__init__.py: add import branches for 3.12, 3.13, 3.14
- cefpython3.setup.py: add PyPI classifiers for 3.12, 3.13, 3.14
- make_installer.py: add .pyd checks and update comments for 3.12, 3.13, 3.14
- build_distrib.py: add (3,12)/(3,13)/(3,14) to version lists
