Clemens Hammacher 01821ab3b6 [test] Stress wasm code gc in "stress_background_compile"
The "stress_background_compile" variant runs on all our bots. We
combine it with testing wasm code GC (which kind of fits into
background compile stressing) to get more coverage for that. Both
features are orthogonal, so we can test both at the same time without
loosing any coverage.
