fix: mark control plane as initialized as soon as endpoints are ready

This should resolve a problem when there's a "deadlock" between CAPI
core MachineController and CACPPT: CAPI core waits for the control plane
to be initialized to start watching workload cluster Nodes to pick up
`.spec.ProviderID` changes, while CACPPT relies on the MachineController
to update the Machine status.
