[PATCH v3 0/4] devtool/recipetool: add support of PEP-517

[Julien Stephan <jstephan@baylibre.com>]

Hello all,

This series adds basic support for PEP-517 in recipetool/devtool, plus somes
others fixes.

Recipetool/devtool selftest passed locally

Missing features:
- extra or optionnal dependencies are not handled
- version number for dependencies are not handled (issue already present
  for the legacy setuptool)
- some projects can declare a minimal pyproject.toml file, and put all
  the metadata in setup.py/setup.cfg/requirements.txt .. theses cases
  are not handled. If a pyproject.toml file is found, assumes it has all
  necessary metadata.

Changes from v2:
- try to use tomllib from python core (since 3.11) and if not available,
  try to import tomli (instead of toml, as tomllib and tomli have both the
  same api)
- improve support for poetry: poetry looks for metadata into the
  "tools.poetry" section instead of the "project" section
- add the selftests for the 3 supported backends. Skip the tests if
  tomliib (python > 3.11) or tomli is not installed
- fix self test failing with the new "python3-" prefix added to
  recipetool for python recipes
