Remove unregistered types from supported target types

[bison]

This checks for errors resulting from unregistered types when
initializing the MachineAutoscaler reconciler and removes them from
the list of supported target types.

This might hide the case where a user forgets to deploy machineset crd. Worth documenting it somewhere. Or, maybe to make at least one of machineset or machinedeployment crds exists. If not, fail?

I don't want to try to do anything too clever, but we could check that there is at least one supported type found otherwise return an error. Does that sound like a reasonable compromise?
