Continuation of https://github.com/payloadcms/payload/pull/12265. Currently, using `select` on new relationship virtual fields: ``` const doc = await payload.findByID({ collection: 'virtual-relations', depth: 0, id, select: { postTitle: true }, }) ``` doesn't work, because in order to calculate `post.title`, the `post` field must be selected as well. This PR adds logic that sanitizes the incoming `select` to include those relationships into `select` (that are related to selected virtual fields) --------- Co-authored-by: Dan Ribbens <dan.ribbens@gmail.com>
