Setup ArrayLength transform for MSL benchmark 

Some of the benchmark shaders when run with the MSL backend are
currently failing because the robustness transform is injecting the
arrayLength method but there is no configuration for running the
arrayLength transform.

This Cl adds some default configuration to the MSL bench to make a slot
available for each possible value. It just always makes them available
such that all shaders work correctly.
