Introduce the testsuite `--with-langkit-python` option so that it is possible to have: * one interpreter with the e3 distribution (to run the testsuite), * one interpreter with Langkit installed (to run lkm and the various scripts using Langkit modules), * one bare interpreter to import Langkit-generated libraries.
