Introduce hashScriptWithPrefix which produces the ScriptHash corresponding to a SerialisedScript

[colll78]

The old versions of PlutusLedgerApi exposed the function scriptHash which could be used to produce the ScriptHash associated with a given SerialisedScript. The fact that the new PlutusLedgerApi does not expose such a function means these projects are forced to implement their own variant of the function (which often involves introducing crypto/hashing library dependencies) or introduce additional heavy dependencies such as CardanoApi. This PR introduces the function hashScriptWithPrefix to PlutusLedgerApi.Common so that downstream applications can avoid redundant work.
