  2. Implement CheckMetadataHash extension (#4274)

    This implements the `CheckMetadataHash` extension as described in
    [RFC78](https://polkadot-fellows.github.io/RFCs/approved/0078-merkleized-metadata.html).
    
    Besides the signed extension, the `substrate-wasm-builder` is extended
    to support generating the metadata-hash.
    
    Closes: #291
