Fix test failures

[cymbalrush]

Fixes two issues

• Add model is now x + y earlier it used to be

int z = x + y;
z = z + x;
z = z + x;
z = z + z;

• CoreML delegate was loading model manager at static initialization and there is a chance that executorch runtime might not have been initialized. ETCoreMLModelManagerDelegate loads it lazily, so that the runtime is guaranteed to be initialized.
