Bring back signature batch verification but with the new name background verification.
Indeed, batch verification - in the cryptographic sense - is a different feature, and only exists for certain types of signatures.
Batch verification is currently only implemented for signatures of type sr25519. For the other types of signatures (ed25519 and ecdsa), each signature is verified alone but in a background task.
Some questions about the design:
Added an optimization suggested by @crystalin: in case the first extrinsics are particularly long to run, the background tasks that check the signatures will do nothing for a while, which is suboptimal.
It is more optimal to spawn all the signatures to be checked in the background before starting to run the extrinsics.
Closes paritytech/polkadot-sdk#351
