Fix VoidRep handling in ghci debugger

'go' inside extractSubTerms was giving a bad result given a VoidRep,
attempting to round towards the next multiple of 0.
I don't understand much about the debugger but the code should be better
than it was.

Fixes #24306

VoidRep-related refactor

* In GHC.StgToByteCode, replace bcIdPrimId with idPrimRep,
  bcIdArgRep with idArgRep, atomPrimRep with stgArgRep1.
  All of them were duplicates.
* In GHC.Stg.Unarise, we were converting a PrimRep to a Type and back to
  PrimRep. Remove the calls to primRepToType and typePrimRep1 which cancel out.
* In GHC.STG.Lint, GHC.StgToCmm, GHC.Types.RepType we were filtering out
  VoidRep from the result of typePrimRep. But typePrimRep never returns
  VoidRep - remove the filtering.

Remove VoidRep from PrimRep, introduce PrimOrVoidRep

This introduces

data PrimOrVoidRep = VoidRep | NVRep PrimRep

changes typePrimRep1 to return PrimOrVoidRep, and adds a new function
typePrimRepU to be used when the argument is definitely non-void.
Details in Note [VoidRep] in GHC.Types.RepType.

Fixes #19520
