Remove createMountItem code

Summary:
Now that pre-allocation of views update props, we can just force the execution of "pre-allocation" instead of "create" mount item.

This diff removes the methods that were used by view creation

This way we reduce the amount of mountItems that are created during commit phase.
This should improve TTI (I'm running a MobileLab)
