Nikolaos Papaspyrou f81430caa9 [heap] Enable conservative stack scanning on tests
Since its introduction (behind a compile-time flag), conservative stack
scanning was disabled by default on tests. This CL inverts this logic,
enabling CSS by default for all tests that do not define an explicit
scope to disable it.
