Add MuHash3072 implementation

Summary:
General context (see core#18000):

This is a step in the way of implementing an index of coin statistics with the goal of making the response time of the gettxoutsetinfo RPC call dramatically faster. Currently, this RPC is scanning the full UTXO set every time it is called which makes it hard to use for users that want to continually check the coin supply or compare UTXO set hashes between different nodes. It is especially challenging in periods of multiple quickly mined blocks, even relatively fast machines.
