Add FSimViaModelTag

[BichengYing]

The motivation of creating this tag is for the qcc/translate part. We can use this tag to control which implementation gate we want to translate it into.

Thanks, Bicheng!

nit: Would it make sense to be more specific in the name, e.g. FSimViaPolyModelTag?

[BichengYing]

FSimViaModel is also the name used in the pyle. (I wish I thought twice on this name). But maybe without Poly is preferred -- in case we have other modeling approach to do the implementation in the future.
