power: Simplify dark resume code.
Replace powerd's DarkResumePolicy class with
DarkResumeInterface. A DarkResumeStub implementation will be
used by tests for a following change to Suspender. The new
interface exposes a simple PrepareForSuspendAttempt() method
that returns the action that should be taken.
Also remove the unused dark_resume_battery_margins pref,
update dark resume unittests to use PowerSupplyStub, and
expand test coverage.
BUG=chromium:384488
TEST=updated tests; also manually tested on link with the
dark_resume_suspend_durations pref set to "0.0 10"
