Reduce icon/text simultaneously when cellHeight is not enough for largest display size

- Follow-up of http://ag/20691430
- Reduce iconDrawablePaddingPx to further recover space
- Then proportional reduce both iconSizePx and iconTextSizePx
- This will result in larger icon/text size in px when going from larger to largest for most devices
- For extremely large desnity (> largest for most devices), iconSizePx/iconTextSizePx will inevitably reduce due to smaller availalbe space

Fix: 264149604
Test: test different density between larger and largest, check that icon/text size continues to grow in px
