One of the main use cases of PartialExtrinsic is that you can build it, then go and obtain a signature from elsewhere (quite possibly asynchronously), and then hand the signature back to the PartialExtrinsic to build the final extrinsic to submit.
PartialExtrinsic didn't implement Send previously, but with this PR it does. An example is also added to prove/show this.
