This PR reverts #2280 which introduced `TransactionExtension` to replace `SignedExtension`. As a result of the discussion [here](https://github.com/paritytech/polkadot-sdk/pull/3623#issuecomment-1986789700), the changes will be reverted for now with plans to reintroduce the concept in the future. --------- Signed-off-by: georgepisaltu <george.pisaltu@parity.io>
