Simplify and fix `AtomicCounter`

`AtomicCounter` was slightly race-y on 32-bit platforms because it
increments the high `AtomicUsize` independently from the low
`AtomicUsize`, leading to a potential race where another thread
could observe the low increment but not the high increment and see
a value of 0 twice.

This isn't a big deal because (a) most platforms are 64-bit these
days, (b) 32-bit platforms aren't super likely to have their
counter overflow 32 bits anyway, and (c) the two writes are
back-to-back so having another thread read during that window is
very unlikely.

However, we can also optimize the counter somewhat by using the
`target_has_atomic = "64"` cfg flag, which we do here, allowing us
to use `AtomicU64` even on 32-bit platforms where 64-bit atomics
are available.

adaptation.

Avoid redundant `{channel,node}_announcement` signature checks

If we receive `{channel,node}_announcement` messages which we
already have, we first validate their signatures and then look in
our graph and discover that we should discard the messages. This
avoids a second lock in `node_announcement` handling but does not
impact our locking in `channel_announcement` handling. It also
avoids lock contention in cases where the signatures are invalid,
but that should be exceedingly rare.

For nodes with relatively few peers, this is a fine state to be in,
however for nodes with many peers, we may see the same messages
hundreds of times. This causes a rather substantial waste of CPU
resources validating gossip messages.

Instead, here, we change to checking our network graph first and
then validate the signatures only if we don't already have the
message.

Remove AvailableBalances::balance_msat

The ChannelMonitor::get_claimable_balances and ChainMonitor::get_claimable_balances
methods provide a more straightforward approach to the balance of a channel, which
satisfies most use cases. The computation of AvailableBalances::balance_msat is
complex and originally had a different purpose that is not applicable

Finish closing channel after async closing signed

In addressing a followup to test reconnection during closing negotation
with async signing, we change things to only return a `ShutdownResult`
when we actually finish shutting down the channel, i.e. we have the
signature ready to send the final closing signed. This slightly
simplifies the logic where we would shutdown our channel
prematurely before we got the final signature. This also means
that we don't push multiple `ChannelClosed` events if we receive closing
signed, reconnect, and receive closing signed again.
