Ensure Keyguard classes use display-aware context

This commit updates all classes in com.android.systemui.keyguard to utilize a @ShadeDisplayAware annotated context. This change prepares for the potential movement of the shade window to a different display, ensuring correct inflation and rendering of keyguard elements.

A linter will be implemented shortly to enforce the use of this annotated context and prevent issues with non-annotated contexts/resources.

Currently, this change has no functional impact as the feature flag is disabled. The @ShadeDisplayAware context remains equivalent to the @Application context.
