Add test for multi-display cutout handling in SysUICutoutProvider

Adds a unit test to verify that `SysUICutoutProviderImpl` correctly uses the display associated with its injected `@DisplayAware` context.

The test simulates a multi-display scenario by creating two instances of the provider: one for a display with a cutout and one for a display without. It then asserts that each provider returns the correct cutout information for its respective display, confirming that the behavior is dependent on the injected context.
