[FRAME] VersionedCall

[xlc]

Previous discussion paritytech/substrate#12740 (comment)

We should introduce a VersionedCall that's opaque Call + transaction_version and it can validate stored transaction_version with current version and report error on mismatching.

And replace all stored calls to use VersionedCall to prevent unexpected bad execution due to breaking transaction version.

Hello! I would like to take this up with your help. Is this still available?

I don't think anyone else is working on this so it is available
But before you start coding, please share here how you plan to implement this just so we can help to ensure it is on the right direction.
The last thing I want to see is you make a huge PR making breaking changes to 5 pallets
