This PR adds a note to the multiprocessing module's documentation about using "frozen" executables with the 'spawn' and 'forkserver'start methods.

This patch simply documents that this should be avoided. I hope it can be applied to the docs for previous Python versions as well (at least 3.7?), as all versions since 3.4 suffer from the issue?

I previously proposed a patch for the problem in PR #5195, but I imagine that will need to be revised and updated for 3.8.

@Mariatta, I noticed you added the backport labels to this a while back. Anything I can do to move this along?

I removed the " needs backport to 3.6" label, the 3.6 branch no longer accept bugfixes (only security fixes are accepted): https://devguide.python.org/#status-of-python-branches

@vstinner, anything I ought to do to get this in to 3.7+? This is an outstanding problem in those releases.
