pw_build: Generate setup.cfg files

Modify generated_python_package to create setup.cfg files instead of
setup.py files. This will make for easier parsing of package data by
other build tooling.

pw_python_package's generate_setup option has been updated to follow
setup.cfg structure. Relevant sections should be nested in the correct
scope. For example here is the old format:

generate_setup = {
  name = "a_nifty_package"
  version = "1.2a"
  install_requires = [ "a_pip_package" ]
}

New format:

generate_setup = {
  metadata = {
    name = "a_nifty_package"
    version = "1.2a"
  }
  options = {
    install_requires = [ "a_pip_package" ]
  }
}

This will generate a setup.cfg similar to the example here:
