[stubs] Unify (and optimize) implementation of ToObject.

This is the initial (big) step towards a more uniform implementation of
the ToObject abstract operation (ES6 7.1.13), where we have a fallback
implementation in JSReceiver::ToObject() and a fast (hydrogen) CodeStub
to deal with the fast case (we should be able to do more cleanup on this
in a followup CL). For natives we expose the abstract operation via a
%_ToObject intrinsic, also exposed via a macro TO_OBJECT, that unifies
the previous confusion with TO_OBJECT_INLINE, ToObject, TO_OBJECT,
$toObject and %$toObject. Now the whole implementation of the abstract
operation is context independent, meaning we don't need any magic in the
builtins object nor the native context.

Fix the failure when enabling v8 profiler or vtune profiler in chromium.

   When enabling the v8 profiler (Using the following command parameters: --js-flags=--prof)
   or vtune profiling in chromium. it will break. This failure is introduced by this CL:
   https://codereview.chromium.org/1218863002.

   The reason is that V8 will enable the JITted code logging if --prof is set for V8. And under
   this condition, the function Logger::LogCodeObjects() will be invoked and it will trigger a
   mark-compact GC when deserializing the snapshot. This GC will use MemoryReducer to post a
   delay task by invoking V8Platform::CallDelayedOnForegroundThread() function. But at this point
   V8 isolation is still under initialization and the PerIsolationData of this isolation has not
   been created. (isolation_holder.cc:39~40 line). This leads to V8Platform::CallDelayedOnForegroundThread()
   failure because of segment fault.

   According to my understanding, I proposed the following fix. If the heap deserialization has not
   be completed, it does not post the delay task for next GC.

[d8 Workers] Fix bug creating Worker during main thread termination

When the main thread terminates, it forcibly terminates all Worker threads.
When this happens, the threads objects were only half-created; they had a
JavaScript Worker object, but not a C++ worker object.

This CL fixes that bug, as well as some other fixes:
* Signatures on Worker methods
* Use SetAlignedPointerFromInternalField instead of using an External.
* Remove state_ from Worker. Simplify to atomic bool running_.

[stubs] Also handle properties of the JSBuiltinsObject in the fast case.

We can apply the shortcut used for data properties of the JSGlobalObject
to builtin properties as well. This mostly affects the custom properties
we use for the Math functions (i.e. rngstate for Math.random() and kMath
for sin, cos and friends).

Drive-by-fix: Also mark the internal builtin typed arrays properties
(rngstate, kMath and rempio2result) as READ_ONLY, as they should not be
touched after genesis.
