Prefetch versions of the gather APIs. Essentially the same as gatherVector but has an extra enum and does not return anything.

This serves as a reminder for when your PR is modifying a ref *.cs file and adding/modifying public APIs, please make sure the API implementation in the src *.cs file is documented with triple slash comments, so the PR reviewers can sign off that change.
