Pull request description:

  ## Additional Information

  * When backporting [bitcoin#23046](https://github.com/bitcoin/bitcoin/pull/23046), it was discovered that there has been a longstanding bug in `CDeterministicMNManager::MigrateDBIfNeeded`(`2`)`()` that flagged a database taken from an older version for failing its "previous migration attempt", requiring the database to be fully rebuilt through a reindex.

    This occurred because the older database would be read pre-DIP3 in `MigrateDBIfNeeded()`, which then caused the migration logic to write the new best block ([source](3f0c2ff324/src/evo/deterministicmns.cpp (L1236-L1241))) (the legacy best block is erased before the DIP3 condition is checked, [source](3f0c2ff324/src/evo/deterministicmns.cpp (L1233))) but while it completed the transaction ([source](3f0c2ff324/src/evo/deterministicmns.cpp (L1240))), critically, it didn't write it to disk (example of writing to disk, [here](3f0c2ff324/src/evo/deterministicmns.cpp (L1288-L1292))).

    This meant that when it was read again by `MigrateDBIfNeeded2()`, it saw three things a) there is no new best block (because it didn't get written), b) there is no legacy best block (because it gets erased before the new best block is written) and c) that the chain height is greater than 1 (since this isn't a new datadir and the chain has already advanced), it concludes that it was a botched migration attempt and fails ([source](3f0c2ff324/src/evo/deterministicmns.cpp (L1337-L1343))).

    This bug affects v19 to `develop` (`3f0c2ff3` as of this writing) and prevents `feature_txindex_compatibility.py` from working as expected as it would migrate legacy databases to newer versions to test txindex migration code and get stuck at unhappy EvoDB migration logic, to allow the test to function properly when testing against the latest version of the client, this bug has been fixed as part of this PR.

  * In [bitcoin#23046](https://github.com/bitcoin/bitcoin/pull/23046), version v0.17 was used as the last version to support legacy txindex as the updated txindex format was introduced in [dash#4178](https://github.com/dashpay/dash/pull/4178) (i.e. after v0.17) and the version selected for having migration code in it (note, migration code was removed in [dash#6296](https://github.com/dashpay/dash/pull/6296), so far not included as part of any release) was v18.2.2 despite the range being v18.x to v21.x was a) due to the bug mentioned above affecting v19.x onwards and b) v18.2.2 being the latest release in the v18.x lifecycle.

    * The specific version number used for v0.17 is `170003` as the binaries corresponding to `170000` are not populated in `releases/`, which causes a CI failure ([source](https://gitlab.com/dashpay/dash/-/jobs/8073041955#L380))

  * As of `develop` (`3f0c2ff3` as of this writing), `feature_pruning.py` was broken due to changes in Core that were not adjusted for, namely:
    * The enforcement of `MAX_STANDARD_TX_SIZE` ([source](3f0c2ff324/src/policy/policy.h (L23-L24))) from DIP1 onwards ([source](3f0c2ff324/src/validation.cpp (L299-L301)))  resulting in `bad-txns-oversize` errors in blocks generated for the test as the transactions generated are ~9.5x larger than the now-enforced limit ([source](3f0c2ff324/test/functional/feature_pruning.py (L48C51-L48C57))), this is resolved by pushing the DIP1 activation height upwards to `2000` (the same activation height used for DIP3 and DIP8).
    * Change in subsidy logic in v20 ([source](3f0c2ff324/src/validation.cpp (L1073-L1082))) that results in `bad-cb-amount` errors, this is resolved by pushing the v20 activation height upwards.

    Additionally, an inopportune implicit post-`generate` sync ([source](3f0c2ff324/test/functional/feature_pruning.py (L215))) also causes the test to fail. Alongside the above, they have been resolved in this PR.

  * As of `develop` (`3f0c2ff3` as of this writing), `bench_dash` crashes when running the `AssembleBlock` benchmark. The regression was traced back to [bitcoin#21840](https://github.com/bitcoin/bitcoin/pull/21840) (5d10b41) in [dash#6152](https://github.com/dashpay/dash/pull/6152) due to the switch to `P2SH_OP_TRUE`.

    This has been resolved by reverting this particular change.
