[HW] HWModule (et. al.) should have separate symbol and name to be emitted

Given all the talk about the mistake of conflating symbols with names, I had assumed that this had been fixed in the HW dialect. Is there some reason it hasn't? Or is this just waiting on someone to do it?

Start by reading the HW dialect implementation and the surrounding discussion about conflating symbols with names. Determine how HWModule and related entities currently represent and emit these concepts. Done means the required separation is designed and implemented consistently, with agreement on the intended behavior.
