ARROW-9258: [FORMAT] Add V5 MetadataVersion to Schema.fbs Version V4 is backwards compatible (with compatibility code for reading unions), but V5 is primarily about guaranteeing that the forward compatibility additions have the intended effect. Additionally the IPC serialization format for unions has changed between V4 and V5.
