Pull request description:

This mode ('createwallet {"disableprivatekeys": true}') is intended for a sane pure watch-only mode, ideal for a use-case where one likes to use Bitcoin-Core in conjunction with a hardware-wallet or another solutions for cold-storage.

Since we have support for custom change addresses in `fundrawtransaction`, pure watch-only wallets including coin-selection are possible and do make sense for some use cases.

This new mode disables all forms of private key generation and ensure that no mix between hot and cold keys are possible.

src/wallet/rpcwallet.cpp
3511 ↗	(On Diff #13793)	The functional cast does work, but to my knowledge its a generally less safe casting method because it tries all cast types and uses which ever one works first (I believe the first three it tries are const, static, and then dynamic casts). In this case, it would likely end up as a static cast. I will be reverting to the functional cast because this is a rather trivial change and there is no need to give ourselves ownership of this code on the off chance that Core makes some changes that affect this code.

Reverted static_cast to functional cast to prevent issues of code ownership and reformatted a comment.
