Merge bitcoin/bitcoin#31403: test: Call generate RPCs through test framework only

fa6e599 test: Call generate through test framework only (MarcoFalke)

Pull request description:

  The generate RPCs are special in that they should only be called by the test framework itself. This way, they will call the sync function on the nodes, which can avoid intermittent test issues. Also, when the sync is disabled, it will happen explicitly by setting the `sync_fun`.

  Apply this rule here, so that all generate calls are written consistently.
