Reland "[TaskEnvironment] Complete migration with header rename"

This is a reland of 18947083c7e75ec6d5e8c3b729515d83bde41c59

The move_source_file.py script's formatting rules incorrectly
formatted services/device/generic_sensor/platform_sensor_and_provider_unittest_win.cc
after all. But we also can't rely 100% on git cl format (crbug.com/997063)
so I ended up performing a git cl format && git add -up
(+interactive addition of missing blank line after foo.h when included
from top of foo.cc)

Also added
$ tools/git/move_source_file.py net/test/test_with_scoped_task_environment.h net/test/test_with_task_environment.h

> This CL uses --bypass-hooks to avoid having to git cl format because
