Review comment:
In other `Target`s they get PrimFunc's which are essentially:
```
{ [Host Module] -> [Device Lib Module] } -> [Device]
```
So conceptually it makes sense to do:
```
{ [Host Module] } -> [Lib]
```
For CMSIS-NN and other library targets, as TVM is hosting the library - I
think, would be interested in @manupa-arm's view here.
