[master] RFR: Enforce +UseCompressedClassPointers [v2]

> This change force-enables +UseCompressedClassPointers. This is required for the next step where we want to store the compressed class pointers into object headers. The change also removes test configurations that explicitely disable CCP.
> In the long run, we would remove the flag altogether, but not now.
> Testing:
>  - [x] tier1
>  - [x] tier2
