This release allows building contracts with recent (> 1.69) Rust toolchains which can emit
signextWasm instructions. An extra pass is added towasm-optwhich "lowers"signextinstructions to MVP compatible instructions. The resulting binaries can therefore be
deployed to chains with an older version of
pallet-contractswhich does not yet supportthose instructions.
