Better wasm support

[Niederb]

I realized that with the current polkadot version we can support additional features for WebAssembly 🥳

Run a cargo update and add test for new wasm target/features. I also had to revert changes related TxExtension. There is currently a back and forth regarding this in polkadot:

• PR https://github.com/paritytech/polkadot-sdk/pull/2280
• Revert of the PR: https://github.com/paritytech/polkadot-sdk/pull/3665
• Revert of the revert: https://github.com/paritytech/polkadot-sdk/pull/3685
