cc: Fix data race in cc::TaskState::IsFinished.

The https://codereview.chromium.org/1866043006/ caused data race, as
the worker and origin threads try to access the Task::state() at the
same time. The member to be accessed on origin thread is now kept
different as it was previously. Now Task::state() is used in worker
thread. It also used in origin thread, when it is safe to be used.
e.g. Task has been processed completely by task graph runner.
