crosvm is switching the import style to use one import per line. While more verbose, this will greatly reduce the occurence of merge conflicts going forward. Note: This is using a nightly feature of rustfmt. So it's a one-off re-format only. We are considering adding a nightly toolchain to enable the feature permanently.
