Merge bitcoin/bitcoin#23725: test: fix feature_coinstatsindex.py --descriptors and add to test runner

61fb410c0d test: add feature_coinstatsindex.py --descriptors to test_runner.py (Sebastian Falbesoner)
50b044a88e test: fix test feature_coinstatsindex.py for descriptor wallets (Sebastian Falbesoner)

Pull request description:

  The functional test feature_coinstatsindex.py currently fails on master branch, if descriptor wallets are used (argument `--descriptors`; or if BDB is not compiled, see https://github.com/bitcoin/bitcoin/pull/23682#issuecomment-989827592). This is due to the fact that different change output types are used for created transactions (P2WPKH for legacy wallets, P2TR for descriptor wallets; the former doesn't have a ScriptPubKeyMan for bech32m), resulting in different tx sizes and hence also fees. Fix this by explicitely setting the output type via passing both `-addresstype=bech32` and `-changetype=bech32` as argument. The former would not be needed by now, but makes the test more deterministic and avoids a failure if bech32m becomes the default address type.

  Should further pave the way for #23682.
