This sets `useLineEndingsForPlatform=true` for basic completion tests that now pass, but leave it set to `false` in `AbstractCompletionDriverTest` for now because there are a large number of failures in other tests that use that base class due to hard-coded offsets. It also updates the format tests to support this (plus extracts some helpers to reduce the duplication).
