Vincent Fazio 3fed424566 package/python3: use the provided pyc compiler
Previously, we used support/scripts/pycompile.py to generate the pyc
files for the python libraries.

While the script worked, it did not follow the PEP 3147 layout
requirements for py+pyc deployments.

Now, use the package's own compileall.py script. This will follow
PEP 3147 guidelines. It also supports "legacy" pyc only deployments as
described here:
  https://peps.python.org/pep-3147/#case-4-legacy-pyc-files-and-source-less-imports

With this change, we no longer need to hack support for side-by-side pyc
files because files will be deployed as appropriate.

This also has the added benefit of not requiring python3 on the host to
build host-python3.

Fixes: #14911

Subject: [PATCH] Add an option to disable lib2to3
lib2to3 is a library to convert Python 2.x code to Python 3.x. As
such, it is probably not very useful on embedded system targets.
