Implementation of RIPEMD-160 for Plutus Core

[kwxm]

@paluh has provided an implementation of the RIPEMD-160 hash function as a Plutus Core builtin in #6252 and this has been brought up to date with the current state of the main Plutus repository in PR #6378. When this is merged it will satisfy all of the goals of PI objective #6155 except for adding it to the PLC specification and providing end-to-end tests.
