Issue #13237: Forward port from 3.2 of subprocess documentation updates. Needed quite a few adjustments to account for new features coming in 3.3

Issue #13237: Fix formatting error - the legacy shell commands weren't meant to be under the Notes heading

Issue #13237: Forward port subprocess module updates and explicitly document UTF-8 encoding assumption when universal_newlines=True

keyword arguments because, unlike other other functions in the family,
it has a `flags` value at the end of the argument list (which
retains its 0 default).

Issue #13340.

The one interface we commit to maintain is the run module
(a.k.a. the pysetup script).

Running with regrtest does not show spurious output or unrestored
sys.std* objects; sometimes running with make test is different, I’ll
watch the buildbots.

In addition, update the create module to use logging.

When an option is changed on a command object, calling ensure_finalized
for a second time will not run finalize_options again, because
ensure_finalized is a no-op the second time.  By resetting the finalized
attribute, we can be sure that whatever computation takes place in
finalize_options will happen again.

(In test_command_clean, I removed two lines that were a no-op.)

This method was named reinitialize_command in distutils and accompanied
by a comment suggesting to change it to get_reinitialized_command.
Following that, I did the change for distutils2, but it proved
confusing: The Distribution object has an internal cache of command
objects, to make sure only one instance is ever used, and the name
get_reinitialized_command could suggest that the object returned was
independent of that cache, which it was not.  I’m reverting the name
change to make code clearer.
