A replacement of NEP11Payable and NEP17Payable. The essence is the same,
but these standards have official name since

Instead of tick-tocking with sync/async and having an unpredictable data
set we can just try to check for the real amount of keys that be processed
by the underlying DB. Can't be perfect, but still this adds some hard
limit to the amount of in-memory data. It's also adaptive, slower machines
will keep less and faster machines will keep more.
This gives almost perfect 4s cycles for mainnet BoltDB with no tail cutting,
it makes zero sense to process more blocks since we're clearly DB-bound:

2× can be considered, but this calculation isn't perfect for low number of
keys, so somewhat bigger tolerance is preferable for now. Overall it's not
degrading performance, my mainnet/bolt run was even 8% better with this.
Fixes#3249, we don't need any option this way.
Fixes#3783 as well, it no longer OOMs in that scenario. It however can OOM in
case of big GarbageCollectionPeriod (like 400K), but this can't be solved easily.

We're trying to delete less than 1% of data in the default configuration for
mainnet, so it looks like this:
2025-01-14T15:51:39.449+0300 INFO finished MPT garbage collection {"removed": 221115, "kept": 71236766, "time": "5m40.323822085s"}
Spending this much time for this low gain every 10K blocks is far from being
optimal.

RemoveUntraceableBlocks without RemoveUntraceableHeaders is still a valid
configuration and removeOldTransfers() only checks for gcBlockTimes now
for timestamps, so they should always be added. This fixes
2025-01-13T23:28:57.340+0300 ERROR failed to get block timestamp transfer GC {"time": "1.162µs", "index": 20000}
for RemoveUntraceableBlocks-only configurations.

The intention here is to reduce the amount of in-flight changes and prevent
OOM. It doesn't matter what we're doing, persisting or collecting garbage,
what matters is that we're behind the schedule of regular persist cycle.

It doesn't change anything logically, but transfer GC needs to have current
block timestamp for its logic and if we're delaying it with MPT GC it can
more often fail to obtain it:
2025-01-13T16:15:18.311+0300 ERROR failed to get block timestamp transfer GC {"time": "1.022µs", "index": 20000}
It's not critical, this garbage can still be collected on the next run, but
we better avoid this anyway.

This will be used to differentiate full history nodes from state only. Currently
it's just a definition, we can not use it safely on current networks because
nodes will refuse this Version, so actual code using the attribute will be
added in newer versions.

It's more symmetric than the C# counterpart, but the essence is the same: we
can accept capabilities we can't interpret. Refs. https://github.com/neo-project/neo/pull/3639

Solves two problems:
* inability to estimate GAS needed for registerCandidate in a regular way
because of its very high fee (more than what normal RPC servers allow)
* inability to have MaxBlockSystemFee lower than the registration price
which is very high on its own (more than practically possible to execute)

As we are not afraid of duplicates this is not a critical error anymore.
BlockFetcher will take the first returned by search.
