### Description This PR adds some missing column selectors to `NullColumnPartSerde` used by explicit null columns (added in #12279). The `VectorObjectSelector` is used by many vector aggregators when they don't care to deal with dictionary id lookup, so this fixes issues when using these aggregators with explicit null columns. I'm not certain if the `VectorValueSelector` is actually used in practice, but went ahead and added it just in case. This PR has: - [x] been self-reviewed. - [x] added unit tests or modified existing tests to cover new code paths, ensuring the threshold for [code coverage](https://github.com/apache/druid/blob/master/dev/code-review/code-coverage.md) is met. - [x] been tested in a test Druid cluster. -- This is an automated message from the Apache Git Service.
