### Rationale for this change I was looking into #49889 and updated the handling of logical nulls in the `is_valid`, `is_null`, and `true_unless_null` kernels. It turns out there is some prior work here that I didn't see before I starting implementing my fix (#35058, #35036, #37642). For some reason, that work has stalled. ### What changes are included in this PR? This PR updates the `IsValidExec`, `IsNullExec`, and `TrueUnlessNullExec` kernels so that they call out to a new function `SetLogicalNullBits`. The `SetLogicalNullBits` function matches the logic in `ArraySpan::ComputeLogicalNullCount()`. The logic is similar enough that they may be some opportunities for code deduplication in `dict_util.cc` and `ree_util.cc`. ### Are these changes tested? Yes ### Are there any user-facing changes?
