lightning-hsmtool: support extracting the mnemonic from hsm_secret.

Browse Source 
We cannot use the codex32 or raw hex for recovery of 25.12 nodes,
since they will then use the incorrect derivation for all paths, and
be unable to spend (or even find!) their funds.

So implement `getsecret` to replace `getcodexsecret`.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: `lightning-hsmtool`: `getsecret` replaces `getcodexsecret` for modern nodes (gives mnemonic).
Changelog-Deprecated: `lightning-hsmtool`: `getcodexsecret`.  Use `getsecret`.

Inevitably there are features which need to change: either to be generalized, or removed when they can no longer be supported.
