Since we switched to C++14 now, we can use {std::make_unique} instead
of our own {base::make_unique} from {template-utils.h}.

- Remove heap-inl.h includes from places where it looked unnecessary. (This is a
  non-scientific approach, because it's probably pulled in indirectly anyway.)

- Annotate places which include heap-inl.h because they need heap/ internals.

- ACCESSORS legitimately needs heap-inl.h because of Heap::FromWritableHeapObject.

- Add includes to heap/heap-write-barrier(-inl).h

- A bunch of IWYU fixes discovered when working on this CL (includes which were
  missing because heap-inl.h pulls them in indirectly).

Now callers of Heap::CollectGarbage* functions need to
specify the reason as an enum value instead of a string.

Subsequent CL will add stats counter for GC reason.

This change binds each {Cancelable} task to a so-called {CancelableTaskManager},
which is then used to handle concurrent cancelation as well as synchronizing
shutdown for already running tasks.  Since ownership of tasks is transferred to
the platform executing a task (destructor), handling in the manager uses integer
ids. Note that this also mitigates (modulo integer size) the ABA problem.

All handling of {Cancelable} tasks is now encapsulated into the corresponding
manager, which is instantiated for each isolate.
