When creating and inserting strings into the string table, we have to make sure that the writes to the string's fields (including its characters) are not reordered to after the write of the string into the table itself. Thanks TSAN!

Rather than an Object array, use a Tagged_t array to store the elements of the off-heap string table. This matches the old on-heap string table's behaviour, and recovers memory regressions from that work. To be able to do this, this also introduces a new slot type, OffHeapObjectSlot. This is because CompressedObjectSlot assumes that the slot is on-heap, and that it can mask the slot location to recover the isolate root. OffHeapObjectSlot doesn't define an operator*, and instead provides a `load(const Isolate*)` method. The other slots also gain this method so that they can use it in slot-templated functions. Also, the RootVisitor gains an OffHeapObjectSlot overload, which is UNREACHABLE by default and only needs to be defined by visitors that can access the string table. As a drive-by, fix some non-atomic accesses to the off-heap string table, also using the new slot.
