Add source reference to BlindedPathCandidate hop

Blinded paths currently contain a node id for the introduction node.
However, a compact representation will allow a directed short channel id
instead. Update BlindedPathCandidate and OneHopBlindedPathCandidate to
store a NodeId reference from either the NetworkGraph or from the user-
provided first hops.

This approach avoids looking up the introduction node id on demand,
which may not be resolvable. Thus, that would require returning an
Option from CandidateRouteHop::source and handle None accordingly.

Fix race between handshake_complete and timer_tick_occurred

The initial noise handshake on connection establishment must complete
within a single timer tick. This timeout is enforced via
`awaiting_pong_timer_tick_intervals` whenever a timer tick fires while
our handshake has yet to complete. Currently, on an inbound connection,
if a timer tick fires after we've sent act two of the noise handshake
along with our init message and before receiving the counterparty's init
message, we begin enforcing such timeout. Even if we immediately
continue to process the counterparty's init message to complete to
handshake, the timeout enforcement is not cleared. With the handshake
complete, `awaiting_pong_timer_tick_intervals` is now tracked to enforce
a pong timeout, except a ping was never actually sent. If a single timer
tick fires again without having received a message from the peer, or
enough timer ticks fire to trigger the
`MAX_BUFFER_DRAIN_TICK_INTERVALS_PER_PEER` logic, we'll end up
disconnecting the peer due to a timeout for a pong we'll never receive.

We fix this by always resetting `awaiting_pong_timer_tick_intervals`
upon processing our counterparty's init message.

Ensure we read the full TLV stream length when maybe-reading `None`

If we are reading an object that is `MaybeReadable` in a TLV stream
using `upgradable_required`, it may return early with `Ok(None)`.
In this case, it will not read any further TLVs from the TLV
stream. This is fine, except that we generally expect
`MaybeReadable` always consume the correct number of bytes for the
full object, even if it doesn't understand it.

This could pose a problem, for example, in cases where we're
reading a TLV-stream `MaybeReadable` object inside another
TLV-stream object. In that case, the `MaybeReadable` object may
return `Ok(None)` and not consume all the available bytes, causing
the outer TLV read to fail as the TLV length does not match.
