pallet-xcm: Deprecate execute and send in favor of execute_blob…

… and `send_blob` (#3749) `execute` and `send` try to decode the xcm in the parameters before reaching the filter line. The new extrinsics decode only after the filter line. These should be used instead of the old ones. ## TODO - [x] Tests - [x] Generate weights - [x] Deprecation issue -> #3771 - [x] PRDoc - [x] Handle error in pallet-contracts This would make writing XCMs in PJS Apps more difficult, but here's the fix for that: polkadot-js/apps#10350. Already deployed! https://polkadot.js.org/apps/#/utilities/xcm Supersedes #1798 --------- Co-authored-by: PG Herveou <pgherveou@gmail.com> Co-authored-by: command-bot <> Co-authored-by: Adrian Catangiu <adrian@parity.io>
