Provide empty ShadeDisplaysInteractor impl for sysui variants without shade window

This splits ShadeDisplaysInteractor into an interface.

This change facilitates providing a no-op implementation of
`ShadeDisplaysInteractor` for Android variants that do not have
a movable shade window, such as Wear OS or Android TV.

A new Dagger module, `ShadeDisplayAwareWindowWithoutShadeModule`,
is introduced to bind this no-op implementation. This allows
modules that depend on `ShadeDisplaysInteractor` (e.g., classes
within `SceneContainerFrameworkModule`) to function correctly on
these platforms without requiring the full shade window infrastructure.

The Wear component has been updated to include this module.
