fix!: Rotation members calc v19 (#5142)
With 18.2, block
`0000000000000044356e582f9748f9baf084e5b7946e6386b32620d540830fda` is
marked invalid with `bad-qc-invalid`.

## Issue being fixed or feature implemented
While the 19 isn’t active -> Calculate rotation members based on 18.1
code
Once 19 active -> Calculate rotation members based on 18.2 code

feat(llmq): Ensure connections between IS quorums (#4917)
* fix(llmq): Ensure connections between quorums

Every masternode will now "watch" a single node from _every other_ quorum in addition to intra-quorum connections. This should make propagation of recsigs produced by one quorum to other quorums much more reliable.

* fix: Do this only for masternodes which participate in IS quorums

* refactor: rename `CQuorumManager::EnsureQuorumConnections` to better match the actual behaviour

(and avoid confusion with `CLLMQUtils::EnsureQuorumConnections`)

* refactor: move IS quorums watch logic into `CQuorumManager::CheckQuorumConnections`

avoid calling slow `ScanQuorums` (no caching atm) inside the loop

* tests: check that inter-quorum connections are added

* use `ranges::any_of`

feat(llmq): avoid probing mns too often instead of using a tiny window to probe them (#4904)
We only call AddQuorumProbeConnections when a new quorum is intialized. It's possible to miss the 10 minute probe window if Contribute phase takes too long (when 2 blocks were mined in 10+ minutes). 50 minutes should be enough and probing once in 10 minutes should be safe.

llmq: Various fixes and improvements (#4890)
* feat(llmq): Introduce useRotation in LLMQParams

* fix(llmq): Fix IsQuorumRotationEnabled to recognize all dip0024 quorums

* fix(llmq): Do not allow rotation llmqs for `-llmqinstantsend` and non-rotation ones for `-llmqinstantsenddip0024`

* fix(llmq): Unify and fix IsMiningPhase

NOTE: no need for 1 extra block in mining phase for rotation quorums

* chore(llmq): Reduce the number of IsQuorumRotationEnabled calls

* chore(llmq): Improve logging

* feat(llmq): Make `llmq-` threads for rotation quorums distinguishable by quorum index

* fix(llmq): Fix another endless loop in GetQuorumRelayMembers

* throw an error when a llmq type with an incompatible rotation flag is picked for `-llmq...` params

* Add a note about loop conditions

* llmq: Make TransactionRemovedFromMempool the last action for invalid txes, just like we do for orphans with rejected parents

Write to log, send reject msg and (maybe) punish first and only then notify IS about the tx removal. Makes it easier to reason about it when reading logs.

Merge bitcoin#15759: p2p: Add 2 outbound block-relay-only connections (#4862)
* Remove unused variable

* [refactor] Move tx relay state to separate structure

* [refactor] Change tx_relay structure to be unique_ptr

* Check that tx_relay is initialized before access

* Add comment explaining intended use of m_tx_relay

* Add 2 outbound block-relay-only connections

Transaction relay is primarily optimized for balancing redundancy/robustness
with bandwidth minimization -- as a result transaction relay leaks information
that adversaries can use to infer the network topology.

Network topology is better kept private for (at least) two reasons:

(a) Knowledge of the network graph can make it easier to find the source IP of
a given transaction.

(b) Knowledge of the network graph could be used to split a target node or
nodes from the honest network (eg by knowing which peers to attack in order to
achieve a network split).

We can eliminate the risks of (b) by separating block relay from transaction
relay; inferring network connectivity from the relay of blocks/block headers is
much more expensive for an adversary.

After this commit, bitcoind will make 2 additional outbound connections that
are only used for block relay. (In the future, we might consider rotating our
transaction-relay peers to help limit the effects of (a).)

* Don't relay addr messages to block-relay-only peers

We don't want relay of addr messages to leak information about
these network links.

* doc: improve comments relating to block-relay-only peers

* Disconnect peers violating blocks-only mode

If we set fRelay=false in our VERSION message, and a peer sends an INV or TX
message anyway, disconnect. Since we use fRelay=false to minimize bandwidth,
we should not tolerate remaining connected to a peer violating the protocol.

* net_processing. Removed comment + fixed formatting

* Refactoring net_processing, removed duplicated code

* Refactor some bool in a many-arguments function to enum

It's made to avoid possible typos with arguments, because some of them have default values and it's very high probability to make a mistake here.

* Added UI debug option for Outbound

* Fixed data race related to `setInventoryTxToSend`, introduced in `[refactor] Move tx relay state to separate structure`
