The activehdkey record will now be loaded into the wallet as its own member variable. Since the private keys will always be in existing descriptors in the wallet, the key for the active hd key is also pulled out of those descriptors on loading.
We often need to construct a CExtKey given an CExtPubKey and CKey, so implement a constructor that does that for us.

…ster The test creates a wallet on master, downgrades and encrypts the wallet. Then, it tries to open it again on master.
We will need access to a function that sets up a singular DescriptorSPKM, so refactor this out of the multiple DescriptorSPKM setup function.
If WALLET_FLAG_HAS_HDKEY_RECORDS is already set, then it's okay to just
use the hd{c}key records.
Descriptor wallets store an HD master key that is used for new automatically generated descriptors. sethdseed is an existing RPC that can be repurposed to allow the users to set that HD key whenever they want. Using sethdseed with a descriptor wallet sets the HAS_HDKEY_RECORDS flag. Also fixes the whitespace of sethdseed. Best to review this with --ignore-all-space

sethdseedfor descriptor wallets. To be able to usecreatewalletdescriptorwith the other address types, we need a way to change the wallet extended key, and sosethdseedhas been updated and enabled for descriptor wallets. As with legacy wallets, when called without parameters, it will generate a new random master key for the wallet. It can also take a xprv and set that as the master key. It still takes a BIP 32 seed as WIF or as hex as we do for legacy wallets. The seed will be transformed into and stored as a BIP 32 extended key. The latter is to give us greater compatibility with other wallets which often produce non-WIF HD seeds.Split from #25907
