This patch introduces a new LocalIsolate and LocalFactory, which use LocalHeap and replace OffThreadIsolate and OffThreadFactory. This allows us to remove those classes, as well as the related OffThreadSpace, OffThreadLargeObjectSpace, OffThreadHeap, and OffThreadTransferHandle. OffThreadLogger becomes LocalLogger. LocalHeap behaves more like Heap than OffThreadHeap did, so this allows us to additionally remove the concept of "Finish" and "Publish" that the OffThreadIsolate had, and allows us to internalize strings directly with the newly-concurrent string table (where the implementation can now move to FactoryBase). This patch also removes the off-thread support from the deserializer entirely, as well as removing the LocalIsolateWrapper which allowed run-time distinction between Isolate and OffThreadIsolate. LocalHeap doesn't support the reservation model used by the deserializer, and we will likely move the deserializer to use LocalIsolate unconditionally once we figure out the details of how to do this.

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.

TurboFan generates significantly less code than Liftoff for this test, and depending on timing it can happen that we need to generate thousands of functions, which takes some time and occasionally runs into timeouts. Thus disable tier-up for this test, such that we stick with the much longer Liftoff code, and reach the four separate code spaces quicker.

The (now unique)PersistentHandles container follows this path: 1) PersistentHandles created via PersistentHandlesScope inside of CompilationHandleScope 2) Owned by OptimizedCompilationInfo 3) Owned by JSHeapBroker 4) Owned by the broker's LocalHeap 5) Back to the broker for a brief moment (after tearing down the LocalHeap as part of exiting LocalHeapScope) 6) Back to OptimizedCompilationInfo when exiting the LocalHeapScope. There is a special case in GenerateCodeForTesting where the JSHeapBroker will not be retired in that same method. In this case, we need to re-attach the PersistentHandles container to the JSHeapBroker. The identity map of the persistent & canonical handles also gets passed around like the persistent handles. The only difference is that is created in the CanonicalHandleScope (i.e step 1) is different).
