There are numerous checks that don't make much sense to report for deprecated
API, so skip those. This also required updating a few .ignore and .todo files.
Enabling this will ensure that future bindings (and Xcode updates that
change nullability information) are spotted right away.
The binding fixes are **not** complete, i.e. what was done was mostly
to debug the xtro rule and find corner cases. The backlog will be
_ignored_ so the builds won't fail.
