cameraserver: Correct camera1 -> api2 shim layer handling for video stabilization.

For cases where devices support PREVIEW_STABILIZATION but not
VIDEO_STABILIZATION, map PREVIEW_STABILIZATION to the camera2 api.

For cases where both are supported, still map to VIDEO_STABILIZATION.

Bug: 254856553

Test: Make back camera on cuttlefish support only PREVIEW_STABILIZATION;
