This function is always called right after creating the DefaultPlatform,
hence merge it into the constructor.

Follow-up to https://chromium-review.googlesource.com/c/v8/v8/+/941442.
"background" refers to a priority and is inappropriate to refer to
worker threads as many tasks posted to worker threads by v8 are in
fact high priority.
Also took advantage of this rename to make NumberOfWorkerThreads()
return an int instead of size_t. While it is never negative, int is
simpler and Google C++ style guide states to avoid unsigned integers in
such cases (ref. "On Unsigned Integers" @
https://google.github.io/styleguide/cppguide.html#Integer_Types).
The Chromium embedder for that call provided an int which was converted
to size_t for this override and most often casted back down to int on the
v8 side, adding churn, and readability overhead.

There was a data race in the access of the foreground_task_runner_map_.
I protect each access to foreground_task_runner_map_ with a lock now.

This CL implements the TaskRunners in the DefaultPlatform which has been
added recently to the platform API. In addition I changed how task
posting works on the DefaultPlatform.
With this implementation the DefaultPlatform keeps one
DefaultForegroundTaskRunner per isolate, plus one
DefaultBackgroundTaskRunner. The DefaultPlatform owns these TaskRunners
with a shared_ptr, which is also shared with any caller of
GetForegroundTaskRunner or GetBackgroundTaskrunner.
This CL moves the task management from the DefaultPlatform to the
TaskRunners. The DefaultForegroundTaskRunner owns and manages the the
task queue, the delayed task queue, and the idle task queue. The
DefaultBackgroundTaskRunner owns the WorkerThread pool and the
background task queue.
In addition changed many Task* to std::unique_ptr<Task> to document task
ownership.

To enable executing code in a context of a particular time or date (e.g. when
codepath depends on whether it's say evening or New Year) there is a need for
a way to provide it bypassing actual system time.
