gh-119819: Conditional skip of logging tests that require multiprocessing subprocess support

[freakboy3742]

multiprocessing.Manager.Queue requires the use of subprocesses; as a result, it can't run on iOS (and presumably will fail on WASI/Android as well).

#120067 was a previous attempt to address this issue; that fix worked for some platforms, but not iOS.

• Issue: Python 3.12+ breaks backwards compatibility for logging QueueHandler with some Queue classes #119819

This PR appears to fix the test_logging issue, but there's a separate issue with test_datetime. I'm looking into that now; initial indications are that it is completely unrelated to this issue.

[freakboy3742]

I've submitted #120477 to address the test_datetime issue.

@vsajip Just confirming you saw this PR; you dropped some related comments on #120067, but I wasn't sure you saw this one.

Note: switching to '92c168707412b48abb497e5e1dccc8c4d04298d5'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false
