Make `impl_writeable_tlv_based_enum*` actually upgradable

In cc78b77c715d6ef62693d4c1bc7190da990ec0fa it was discovered that
`impl_writeable_tlv_based_enum_upgradable` wasn't actually
upgradable - tuple variants weren't written with length-prefixes,
causing downgrades with new tuple variants to be unreadable by
older clients as they wouldn't know where to stop reading.

This was fixed by simply assuming that any new variants will be
non-tuple variants with a length prefix, but no code write-side
changes were made, allowing new code to freely continue to use the
broken tuple-variant serialization.

Here we address this be defining yet more serialization macros
which aren't broken, and convert existing usage of the existing
macros using non-length-prefixed tuple variants to renamed
`*_legacy` macros.

Note that this changes the serialization format of
`impl_writeable_tlv_based_enum[_upgradable]` when tuple fields are
written, and as such deliberately changes the call semantics for
such tuples.

Only the serialization format of `MessageContext` is changed here
which is fine as it has not yet reached a release of LDK.

adjacent cache lines avoids paying that penalty twice. Thus, here

Cache whether a node is a first-hop target in the per-node state

When processing the main loop during routefinding, for each node,
we check whether it happens to be our peer in one of our channels.
This ensures we never fail to find a route that takes a hop through
a private channel of ours, to a private node, then through
invoice-provided route hints to reach the ultimate payee.

Because this is incredibly hot code, doing a full `HashMap` lookup
to check if each node is a first-hop target ends up eating a good
chunk of time during routing. Luckily, we can trivially avoid this
cost.

Because we're already looking up the per-node state in the `dist`
map, we can store a bool in each first-hop target's state, avoiding
the lookup unless we know its going to succeed.

This requires storing a dummy entry in `dist`, which feels somewhat
strange, but is ultimately fine as we should never be looking at
per-node state unless we've already found a path to that node,
updating the fields in doign so.

not.

This, it turns out, is actually mostly safe - on startup
`ChanelManager` will detect there's a payment it has as unclaimed
but there's a corresponding payment preimage in a `ChannelMonitor`

`ChannelManager` has been persisted after the payment has been
received but prior to the `PaymentClaimable` event being processed
(and the claim itself occurring). This is not always true and
certainly not required on our API, but our
`lightning-background-processor` today does persist prior to event
handling so is generally true subject to some race conditions.

In order to address this we need to use copy payment preimages

state, but this introduces another wrinkle - if one channel makes

`ChannelManager` hasn't been persisted after the payment was
received, we may end up without the preimage on disk.

Here, we address this issue by using the new

block persistence of an RAA `ChannelMonitorUpdate` which may remove
