Allow `RoutingMessageHandler` to signal backpressure

Now that we allow `handle_channel_announcement` to (indirectly)
spawn async tasks which will complete later, we have to ensure it
can apply backpressure all the way up to the TCP socket to ensure
we don't end up with too many buffers allocated for UTXO
validation.

We do this by adding a new method to `RoutingMessageHandler` which
allows it to signal if there are "many" checks pending and
`channel_announcement` messages should be delayed. The actual
`PeerManager` implementation thereof is done in the next commit.
