[turbofan] Make an OptionalOperator for MachineOperatorBuilder. 

This makes usage of the MachineOperatorBuilder more robust, as it will be
an error to request an unsupported operator.

Along the way, I noticed that all 7 platforms support Float32Abs and
Float64Abs. Should make them non-optional in another CL?
