[TaskEnvironment] Mass-migrate away from ScopedTaskEnvironment (1/2)

(well half of them because git cl upload wouldn't let me do
 them all at once...)

This is step #1 of the mass migration. Some of these will be
backported to SingleThreadTaskEnvironment in a later phase.

scoped_task_environment.h will also only move in a follow-up CL.
