Pull request description:
## Additional Information
* Version 2 of BIP152 high-bandwidth mode/compact blocks implements SegWit support.
As Dash does not implement SegWit, there has never been a need to implement v2 (and therefore, have all the code necessary to support both v1 and v2, that gets removed as part of making support v2 only).
* Despite that, the changes surrounding removing support for both versions (that in our case, do not apply as we never have supported v2) refactor the code in other ways and influence their behaviour. In the interest of upstream alignment, those changes have been backported.
* [bitcoin#19776](https://github.com/bitcoin/bitcoin/pull/19776) doesn't seem to work on its own without successive backports, specifically [bitcoin#20799](https://github.com/bitcoin/bitcoin/pull/20799), despite the latter being a later backport.

* The backport of [bitcoin-core/gui#206](https://github.com/bitcoin-core/gui/pull/206) is a continuation of 3e8ba24c87 from [dash#5964](https://github.com/dashpay/dash/pull/5964)
* The backport of [bitcoin#20764](https://github.com/bitcoin/bitcoin/pull/20764) is a continuation of bd934c71eb from [dash#6034](https://github.com/dashpay/dash/pull/6034)
## Breaking changes
* The `getpeerinfo` RPC returns two new boolean fields, `bip152_hb_to` and `bip152_hb_from`, that respectively indicate whether we selected a peer to be in compact blocks high-bandwidth mode or whether a peer selected us as a compact blocks high-bandwidth peer.
High-bandwidth peers send new block announcements via a `cmpctblock` message rather than the usual inv/headers announcements. See BIP 152 for more details.
* Blocks-only mode will use legacy relaying instead of BIP152 high-bandwidth mode
