This PR exposes the *unstable* metadata V16. The metadata is exposed under the unstable u32::MAX number. Developers can start experimenting with the new features of the metadata v16. *Please note that this metadata is under development and expect breaking changes until stabilization.* The `ExtrinsicMetadata` trait receives a breaking change. Its associated type `VERSION` is rename to `VERSIONS` and now supports a constant static list of metadata versions. The versions implemented for `UncheckedExtrinsic` are v4 (legacy version) and v5 (new version). For metadata collection, it is assumed that all `TransactionExtensions` are under version 0.
