Only show low res view on supported small preview

Shared element transition into full preview will flash low res image
which is a white flash with unsupported wallpaper (photos), which is not
needed since the full res image already cached when entering full
preview.

Flag: com.android.window.flags.multi_crop
Bug: 339679893
Test: from small to full preview with different wallpaper
