Collect CCs in CorePrep, including CCs in unfoldings
This patch includes two changes:
1. Move cost centre collection from `SCCfinal` to `CorePrep`, to be able
to collect cost centres in unfoldings. `CorePrep` drops unfoldings, so
that's the latest stage in the compilation pipeline for this.
After this change `SCCfinal` no longer collects all cost centres, but
it still generates & collects CAF cost centres + updates cost centre
stacks of `StgRhsClosure` and `StgRhsCon`s.
This fixes #5889.
2. Initialize cost centre stack fields of `StgRhs` in `coreToStg`. With
this we no longer need to update cost centre stack fields in
`SCCfinal`, so that module is removed.
Cost centre initialization explained in Note [Cost-centre
initialization plan].
Because with -fcaf-all we need to attach a new cost-centre to each
CAF, `coreTopBindToStg` now returns `CollectedCCs`.
