davidot 8da6c01d8f LibJS: Remove the JS_TRACK_ZOMBIE_CELLS option
This feature had bitrotted somewhat and would trigger errors because
PrimitiveStrings were "destroyed" but because of this mode they were not
removed from the string cache. Even fixing that case running test-js
with the options still failed in more places.
