This method should be capable of generating the proper input script for
both regular p2wkh output and p2wkh outputs nested within a regular p2sh
output.
Note that when using this method to sign inputs belonging to the wallet,
the only items of the SignDescriptor that need to be populated are pkScript
in the TxOut field, the value in that same field, and finally the input
derivation between the ephemeral public key in the request and the node's
key specified in the key_desc parameter.</p><divclass="fullcomment"><divclass="comment cmt"><p>DeriveSharedKey returns a shared secret key by performing Diffie-Hellman key
derivation between the ephemeral public key in the request and the node's
key specified in the key_desc parameter. Either a key locator or a raw
public key is expected in the key_desc, if neither is supplied, defaults to
the node's identity private key:
P_shared = privKeyNode * ephemeralPubkey
The resulting shared public key is serialized in the compressed format and
hashed with sha256, resulting in the final key length of 256bit.
