RPC: Derive wallet addresses #20991

Is your feature request related to a problem? Please describe. It is not possible to simply derive the wallet's addresses. I have a need to find the address inside the HD wallet at a given HD path.

Describe the solution you'd like

• Derive address using the node i.e. derivewalletaddress(path) that returns the same as getaddressinfo

Describe alternatives you've considered

• Export xpub - not possible
• Export the seed - dumpwallet only exports to file - cannot be used over network
• deriveaddresses - requires xpub/xprv
• listaddressgroupings + getaddressinfo for every address and find by hdkeypath - This is way too intensive

Additional context Some context I found about xpub exporting explains that this is not possible: https://bitcoin.stackexchange.com/a/90149/106210

This is possible to do with descriptor wallets. listdescriptors can be used to get the descriptors for a descriptor wallet, and those can be used directly in deriveaddresses.
