add ensure_dispatch_as that propagates errors

[sander2]

Addresses paritytech/polkadot-sdk#219

This adds a new function utility.ensure_dispatch_as that is like utility.dispatch_as, except that it propagates errors returned by the wrapped call.

It needs a Polkadot and Cumulus companion. You can just copy the Substrate weights into their weight files to make it compile.

Ok, I made the companion prs. I used the weights of dispatch_as of their respective runtimes, since it's pretty much the same weight.

Okay I updated the MR description to mention them. Let's see if the CI goes green.
