PYTHON-5879 Generate non-coverage companion tasks for macOS/Win64 encryption variants

The cycling algorithm assigns python 3.13/3.14t/3.14 to all three "latest"
topology slots, so every "latest" test-non-standard task gets COVERAGE=1 and
the "cov" tag. Filtering "!.cov" on macOS/Win64 therefore removed ALL latest
tasks, leaving nothing to activate in patch builds.

Fix: emit a non-coverage companion task alongside each coverage task. The
companion has the same python/topology/version but no COVERAGE expansion and no
"cov" tag, so it is selected by the ".test-non-standard !.pypy !.cov" filter
used on macOS/Win64 encryption variants.
