This means it always tells us explicitly whether to keep watching or not,
and we know it's processed it.

This is like `sendonion` but unwraps the onion as the first hop,
avoiding nasty special cases for blinded paths which start with this
node, and also self-pay.
Tests split into multiple ones after Christian's review.

No code changes, just catching up with the BOLT changes which rework our
blinded path terminology (for the better!).
Another patch will sweep the rest of our internal names, this tries only to
make things compile and fix up the BOLT quotes.
1. Inside payload: current_blinding_point -> current_path_key
2. Inside update_add_htlc TLV: blinding_point -> blinded_path
3. Inside blinded_path: blinding -> first_path_key
4. Inside onion_message: blinding -> path_key.
5. Inside encrypted_data_tlv: next_blinding_override -> next_path_key_override

This name is clearer than the old one.
And since the struct contains a string, it's more natural for the
struct to be the tal parent of the string so it's a real object. This means
we need an array of pointers, so each struct can be its own tal object.
wallet_state_change_get is hoisted higher in the code and made static.

We weren't properly notifying that a channel output has been spent in
the case of it being spent in a splice. This fixes the notification side
of the equation, however there's still some issues remaining for the
bookkeeper side (to come).
Changelog-Fixed: We now send a `coin_movement` notification for splice confirmations of channel funding outpoint spends.
This was when we handled pre-TLV onions where the first byte was 0. We haven't
done that for a while: you can tell, because process_onionpacket doesn't use
the parameter at all!

Shahana decided this was the optimal UX path, though I insisted that we still
report the actual problem directly when in dev mode, as a compromise.

I was trying to debug a node with several multiplexed channels, and
was finding it a bit difficult to determine which channel index
matches which result of `listpeerchannels` as well as figuring out
what their status was. This just prints the status in string format
when loading the channel from the DB.
Changelog-Changed: wallet: The channel status is printed when loading it from the DB
This is a difficult transition for us: this string appears in channel
types. We make the transition now in the understanding that it will
be more difficult in future.

Changelog-Deprecated: JSON-RPC: `listpeers` `features` array string "option_anchors_zero_fee_htlc_tx": use "option_anchors" (spec renamed it).
Changelog-Added: JSON-RPC: `listpeers` `features` array string uses "option_anchors" for feature 22/23, following renaming in BOLT 9.
Changelog-Changed: JSON-RPC: `listclosedchannels`, `listpeerchannels`, `openchannel_update`, `openchannel_init`, `fundchannel`, `fundchannel_start` and `multifundchannel`: `channel_type` array `names` now contains "anchors" instead of "anchors_zero_fee_htlc_tx".
Changelog-Changed: lightningd: `--list-features-only` now lists "option_anchors" instead of "option_anchors_zero_fee_htlc_tx".
These were removed from the spec.
We still support existing ones, though we were the only implementation
which ever did, and only in experimental mode, so we should be able to
upgrade them and avoid a forced close, with a bit of engineering...

We used to fire up channeld to send this, but:
1. That's silly, we have all the information to make it ourselves.
2. We didn't do it if there was an error on the channel, which as of 24.02
there always is!
3. When it did work, running channeld *stops* onchaind, indefinitely slowing recovery.

I did some CHANGELOG and git digging to see when these were deprecated, and
some were very old (v0.8.2!). But since they didn't warn users loudly, I
chose to do so this release only.
I renamed ld's `deprecated_apis` to `deprecated_ok` to make sure I
caught them all.

The `struct notification` lost type-safety, but avoided a redundant
string. The string is better, I think.
Since all notifications now contain an object of same name (some have
deprecated fields outside that), we can add helpers to do that, too.
Also, add some const (easy to do now we're typesafe!)

Changelog-Added: hsmd: Added hsmd_forget_channel to enable explicit channel deletion. ([#6987])
Motivation: Previously, a signer prematurely forgetting a channel led
to failures in unresolved channel requests. This update introduces
hsmd_forget_channel, allowing nodes to explicitly notify signers when
a channel is irrevocably resolved and can be safely forgotten. This
ensures synchronized channel cleanup between nodes and signers.
This change maintains backward and forward compatibility. Nodes
explicitly check whether a signer has `WIRE_HSMD_FORGET_CHANNEL`
capability before sending the message. Nodes without
`WIRE_HSMD_FORGET_CHANNEL` capability won't send this message. Signers
capable of handling this message but not receiving it will continue to
use conservative pruning methods.
Fixes#6987
