Merge #20211: Use -Wswitch for TxoutType where possible

Browse Source 
fa650ca7f1 Use -Wswitch for TxoutType where possible (MarcoFalke)
fa59e0b5bd test: Add missing script_standard_Solver_success cases (MarcoFalke)

Pull request description:

  This removes unused `default:` cases for all `switch` statements on `TxoutType` and adds the cases (`MULTISIG`, `NULL_DATA`, `NONSTANDARD`) to `ExtractDestination` for clarity.

  Also, the compiler is now able to use `-Wswitch`.

ACKs for top commit:
  practicalswift:
    cr ACK fa650ca7f1: patch looks correct and `assert(false);` is better than UB :)
  hebasto:
    ACK fa650ca7f1, I have reviewed the code and it looks OK, I agree it can be merged.
