[Task Migration][Extensions] Update SandboxedUnpacker

Update the SandboxedUnpacker class to use the new task scheduling API.

Also remove a call to IsShutdownInProgress() by the SandboxedUnpacker.
This was added to fix https://crbug.com/235525, which was seemingly
caused by tasks to write image files being aborted mid-execution. With
the new task scheduling API, we can solve this by using
TaskShutdownBehavior::SKIP_ON_SHUTDOWN, which will ensure that either
the task will not run, or the task will run until completion.

Since this was the last usage of
SequencedWorkerPool::IsShutdownInProgress(), remove the method in its
entirety.
