Unify cibuildwheel configuration to pyproject.toml

This commit removes all the environment variable usage for default
configuration of cibuildwheel and switches to use the pyproject.toml to
centralize the configuration for all the jobs. Environment variables are
still used for per job custom overrides which don't really fit in the
configuration of the pyproject.toml (mainly cross-build overrides and
GPU configuration).
