[libcxx-commits] [libcxx] [libc++][NFC] Reduce workaround in a `in_place_t` constructor of `optional` (PR #174306)

I think we were technically non-conforming before here. You could have called `optional` with the first argument being convertible to `in_place_t`, but not to `T`. I'm not sure it's worth adding a test for this OTOH, since that's really a deranged case.

Assuming I didn't miss something this would definitely not be NFC though.
