rohd `Logic.zeroExtend` should return `this` if `width` is the same as `newWidth`, and `Swizzle` optimization in SV generation

When zero-extending a signal, if there's nothing to zero-extend, we can just immediately return this rather than go through a Swizzle.

Additionally, when Swizzle gets only one signal with width >0, it shouldn't still add the {} around it.

Call zeroExtend on a Logic with the newWidth equal to the width. Note that it creates a swizzle unnecessarily.
Swizzle two signals, one of which is 0-width, and observe generated SV to contain {} around the one remaining signal.
