platform/surface: aggregator_registry: Add support for tablet mode switch on Surface Pro 8

Browse source 
Add a KIP subsystem tablet-mode switch device for the Surface Pro 8.
The respective driver for this device provides SW_TABLET_MODE input
events for user-space based on the state of the keyboard cover (e.g.
detached, folded-back, normal/laptop mode).
