DanS 2a7fdcc1db wallet: add an optional mnemonic-entropy secret to the key stores ...

Additive plumbing for storing a BIP39 entropy alongside the HD seed, mirroring
how the seed itself is handled through both key store layers: a plaintext member
on CBasicKeyStore, an encrypted pair on CCryptoKeyStore, encryption during the
unencrypted-to-encrypted conversion in EncryptKeys with the plaintext cleared,
and decryption on unlock.

RawHDSeed and CKeyingMaterial are the same secure_allocator vector type, so the
entropy passes through EncryptSecret/DecryptSecret with no adaptation.

Nothing calls this yet; there is no behaviour change.
