```
For the MiniWallet constructor, the two boolean parameters
"raw_script" and "use_p2pk" are replaced by a single parameter of the
newly introduced type MiniWalletMode (derived by enum.Enum), which can
hold the following values:
- ADDRESS_OP_TRUE
- RAW_OP_TRUE
- RAW_P2PK
```
Backport of core#22048.
Depends on D16407.
Note that RAW_OP_TRUE is of no interest for use and wasn't ported.
