Pull request description:

  The utility function is primarily useful to dereference pointer types, which are known to be not null at that time.

  For example, the ArgsManager is known to exist when the wallets are started: https://github.com/bitcoin/bitcoin/pull/18923/files#diff-fdb2a1a1d8bc790fcddeb6cf5a42ac55R503 . Instead of silently relying on that assumption, `Assert` can be used to abort the program and avoid UB should the assumption ever be violated.
