Enforce explicit claims on payments with even custom TLVs

Because we don't know which custom TLV type numbers the user is
expecting (and it would be cumbersome for them to tell us), instead of
failing unknown even custom TLVs on deserialization, we accept all
custom TLVs, and pass them to the user to check whether they recognize
them and choose to fail back if they don't. However, a user may not
check for custom TLVs, in which case we should reject any even custom
TLVs as unknown.

This commit makes sure a user must explicitly accept a payment with
even custom TLVs, by (1) making the default
`ChannelManager::claim_funds` fail if the payment had even custom TLVs
and (2) adding a new function
`ChannelManager::claim_funds_with_known_custom_tlvs` that accepts them.

documentation to account for this.

Note that the enum discriminants were removed because when adding a

De/serialize custom TLVs on `{Inbound,Outbound}OnionPayload`

When serialized, the TLVs in `OutboundOnionPayload`, unlike a normal

to add arbitrary custom TLVs, we aren't able to communicate to our
serialization macros exactly which fields to expect, so this commit
adds new macro variants to allow appending an extra set of bytes (and
modifying the prefixed length accordingly).

Because the keysend preimage TLV has a type number in the custom type
range, and a user's TLVs may have type numbers above and/or below
keysend's type number, and because TLV streams must be serialized in
increasing order by type number, this commit also ensures the keysend
