Merge #14307: Consolidate redundant implementations of ParseHashStr

Browse Source 
9c5af58d51 Consolidate redundant implementations of ParseHashStr (Ben Woosley)

Pull request description:

  This change:
  * adds a length check to all calls to `ParseHashStr`, appropriate given its use to populate
    a 256-bit number from a hex str
  * allows the caller to handle the failure, which allows for the more
    appropriate `JSONRPCError` on failure in `prioritisetransaction` rpc

  Relative to #14288
