Expose information about the extrinsic in the metadata (#4774)
* Expose information about the extrinsic in the metadata This pr exposes some information about the extrinsic used in the runtime via metadata. The following information are exposed: - Version of the extrinsic - List of all signed extensions used by the extrinsic. * Increment `spec_version`
