This is the simplest solution, not the best, but there's significant risk in try to remove the "we have a path" assumption in the code pay code.
Includes removing a `tal_steal` which was incorrect: the buffer has the same lifetime as the plugin, so if we steal it then things get messy when we free the struct payment.

Changelog-Added: Plugins: `pay` will now pay your own invoices if you try.
Previously, the "payment" and "invoice" paths were completely separate, but this now calls both. It bypasses htlc_sets (and thus, cannot do MPP), and bypasses the hook too: the former is tied closely to HTLCs, and the hook is also very htlc-centric.
Includes finishing unfinished sentence in sendpay man page, as a bonus.

Changelog-Added: Plugins: `sendpay` now allows self-payment of invoices, by specifying an empty route.
These tests make assumptions about the presplitter behavior which
we'll remove in the next commit. We remove them here so we don't cause
temporary breaks in the git history.
Previously, our code checked for the presence of the `lightning:`
prefix while decoding a bolt11 string. Although this prefix is valid
and accepted by the core lightning pay command, it was causing issues
with how we managed invoices. Specifically, we were skipping the prefix
when creating a copy of the invoice string and storing the raw invoice
(including the prefix) in the database, which caused inconsistencies
in the user experience.
To address this issue, we need to strip the `lightning:` prefix before
calling each core lightning command. In addition, we should
modify the invstring inside the db with the canonical one.
This commit fixes the issue by stripping the `lightning:` prefix
from the `listsendpays` function, which will improve the
user experience and ensure consistency in our invoice management (see
next commit).

Now we've set everything up, the replacement code is quite simple.
Some tests now have to deal with RBF though, and our rbf tests need work

There are cases (difficult to reproduce with a test) where
a payment will fail one time and succeed later.
As far I understand in this case the groupid field of the payment
is the same, and the only thing that change is the status, so
our logic inside the delpay is ambiguous where it is not
possible to delete a payment as described in https://github.com/ElementsProject/lightning/issues/6114
A sequence of commands that explain the problem is
```
$ lc -k listpays payment_hash=H
{
"pays": [
{
"bolt11": "I",
"destination": "redacted",
"payment_hash": "H",
"status": "complete",
"created_at": redacted,
"completed_at": redacted,
"preimage": "P",
"amount_msat": "redacted",
"amount_sent_msat": "redacted"
}
]
}
$ lc delpay H complete
{
"code": 211,
"message": "Payment with hash H has failed status but it should be complete"
}
```
In this case, the delpay is not able to delete a payment because the
listpays is returning only the succeeded one, so by running the
listsendpays we may see the following result where our delpay logic
will be stuck because it works to ensure that all the payments stored
in the database has the status specified by the user
```

I know this is an unforgivably large diff, but the spec has changed so
much that most of this amounts to a rewrite.
Some points:
* We no longer have "offer_id" fields, we generate that locally, as all
offer fields are mirrored into invoice_request and then invoice.
* Because of that mirroring, field names all have explicit offer/invreq/invoice
prefixes.
* The `refund_for` fields have been removed from spec: will re-add locally later.
* quantity_min was removed, max == 0 now mean "must specify a quantity".
* I have put recurrence fields back in locally.

The "path" is just a message to ourselves. This meets the minimal
requirement for bolt12 invoices: that there be a blinded path (at
least so we can use the path_id inside in place of "payment_secret").

will need this for generating more sophisticated paths.

The goal here is to test the node validation, not whether we can

"sphinx_add_hop" takes a literal hop to include,
"sphinx_add_modern_hop" prepends the length. Now we always prepend a
length, make it clear that the literal version is a shortcut:
