power: Add chipset and board callbacks for sleep hangs
Instead of passing a callback to host_sleep, define overridable board
and chipset callbacks for sleep hang detection.
Introduce a sleep_hang_type enum that identifies the type of sleep hang
(suspend or resume).
These changes make it eaier for boards to implement custom logic to
handle sleep hangs.
BUG=b:218892808

TEST=Observe suspend hang detection on Nipperkin with KI
