Summary: The previous offloading entry type did not fit the current use-cases very well. This widens it and adds a version to prevent further annoyances. It also includes the kind to better sort who's using it. The first 64-bytes are reserved as zero so the OpenMP runtime can detect the old format for binary compatibilitry.
