python-toml: add recipes for python2 and python3

This package is a Python library for parsing and creating TOML [1].

Another python TOML parser library named pytoml already exists in
meta-oe/recipes-devtools/python/python*-pytoml_*.bb but this library is
deprecated and it is explicitly explained to consider using the toml
package instead [2].
