Currently, the logic around whether we called CAddrMan::Connected() for
a peer is spread between verack processing (where we discard inbound
peers) and FinalizeNode (where we discard misbehaving and
block-relay-only peers). Consolidate that logic to a single place.
Also remove the CNode.fCurrentlyConnected bool, which is now
redundant. We can rely on CNode.fSuccessfullyConnected, since the two
bools were only ever flipped to true in the same place.

Pull request description:
This PR does two things:
* Block-relay-only interaction with addrman.
* Calling `CAddrMan::Connected()` on an address that was a block-relay-only peer causes the time we report in `addr` messages containing that peer to be updated; particularly now that we use anchor connections with a our block-relay-only peers, this risks leaking information about those peers. So, stop this.
* Avoiding calling `CAddrMan::Good()` on block-relay-only peer addresses causes the addrman logic around maintaining the new and tried table to be less good, and in particular makes it so that block-relay-only peer addresses are more likely to be evicted from the addrman (for no good reason I can think of). So, mark those addresses as good when we connect.
* Fix test-before-evict bug. There's a bug where if we get a collision in the tried table with an existing address that is one of our current peers, and the connection is long-lived enough, then `SelectTriedCollisions()` might return that existing peer address to us as a test-before-evict connection candidate. However, our logic for new outbound connections would later prevent us from actually making a connection; the result would be that when we get a collision with a long-lived current peer, that peer's address is likely to get evicted from the tried table. Fix this by checking to see if a test-before-evict candidate is a peer we're currently connected to, and if so, mark it as `Good()`.

3d0556d410 Increase feature_taproot inactive test coverage (Pieter Wuille)
525cbd425e Only relay Taproot spends if next block has it active (Pieter Wuille)
Pull request description:
There should be no change to mempool transaction behavior for witness v1 transactions as long as no activation is defined. Until that point, we should treat the consensus rules as under debate, and for soft-fork safety, that means spends should be treated as non-standard.
It's possible to go further: don't relay them unless the consensus rules are actually active for the next block. This extends non-relay to the period where a deployment is defined, started, locked in, or failed. I see no downsides to this, and the code change is very simple.

A string literal `"abc"` contains a terminating `\0`, so that is 4
bytes. There is no need to write `"abc\0"` unless two terminating
`\0`s are necessary.
`std::string` objects do not internally contain a terminating `\0`, so
`std::string("abc")` creates a string with size 3 and is the same as
`std::string("abc", 3)`.
In `"\01"` the `01` part is interpreted as one number (1) and that is
the same as `"\1"` which is a string like `{1, 0}` whereas `"\0z"` is a
string like `{0, 'z', 0}`. To create a string like `{0, '1', 0}` one
must use `"\0" "1"`.
Adjust the tests accordingly.

Outbound peer logic prevents connecting to addresses that we're already
connected to, so prevent inadvertent eviction of current peers via
test-before-evict by checking this condition and marking current peer's
addresses as Good().
Co-authored-by: John Newbery <john@johnnewbery.com>
Being able to invoke Good() is important for address management (new vs tried
table, tried table eviction via test-before-evict). We mitigate potential
information leaks by not calling Connected() on these peer addresses.
