Revert "[static-roots] Allow creating isolates from existing r/o snapshot"
This reverts commit 331c577e1d.
Reason for revert: https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20-%20debug%20-%20single%20generation%20-%20builder/9912/overview
Original change's description:
> [static-roots] Allow creating isolates from existing r/o snapshot
>
> This adds the ability to create an isolate from scratch, except the
> read only roots, which are initialized from a read_only_data snapshot.
> To do this we split the heap setup in a read/only part and the rest.
> The goal of these changes is to later support writing serializer tests,
> even if the read only roots are static and have to be loaded from a
> fixed snapshot.
>
> Bug: v8:13466
