b2cd1db406 Don't use CEvoDB in CDKGSessionManager and instead use llmqDb 
Contributions are not part of on-chain consensus and shouldn't be stored in
CEvoDB.

e2cad1bd69 Introduce global llmq::llmqDb instance of CDBWrapper 
This DB is for LLMQ related data that is not part of on-chain consensus.
This for example included LLMQ secret key shares and recovered signatures.

2a7a5c6338 Only sign ChainLocks when all included TXs are "safe" 
Safe means that the TX is either ixlocked or known since at least 10
minutes.

Also change miner code to only include safe TXs in block templates.

0a5e8eb862 Move ChainLock signing into TrySignChainTip and call it periodically 
Later commits will introduce checks for "safe TXs" which might abort the
signing on first try, but succeed a few seconds later, so we periodically
retry to sign the tip.

0364e033a7 Implement 2-stage commit for CEvoDB to avoid inconsistencies after crashes (#2744) 
* Let Commit() return void

The boolean return value will loose its meaning in the next commit

* Implement 2-stage commits for CDBTransaction and CScopedDBTransaction

CDBTransaction is changed to allow CDBBatch, CDBWrapper and other
CDBTransactions as parent instead of just CDBWrapper. This in turn allows
to implement multi-staged commits in CEvoDB.

We now have the "current transaction" which is started and ended (commit
or rollback) for each call to Connect-/DisconnectBlock. When the current
transaction is committed, it moves its contents into the "root transaction"
instead of directly writing to CDBWrapper.

CommitRootTransaction() then handles the final commitment to CDBWrapper. It
is called at the same time when the chainstate is flushed to disk, which
guarantees consistency between chainstate and CEvoDB.

* Allow to efficiently move values into parent transactions to avoid copies

When CDBTransaction<CDBTransaction<...>>::Commit() is called, we can avoid
copying values from this transaction to the parent transaction and instead
pass values by rvalue and let the contents be moved.

* Revert "Force FlushStateToDisk on ConnectTip/DisconnectTip while not in IBD (#2560)"

This reverts commit 6dfceaba5a.

43612a2720 Only include selected TX types into CMerkleBlock (#2737) 
It was reported on iOS that CMerkleBlock sometimes included the dummy
quorum commitments introduced with v13, which led to banning of nodes as
these were not supported/expected there.

We should in general only include TXs here that are of interest for SPV
nodes, so we should maintain the list of allowed TX types.
