CDD: Allow rectangular display with rounded corners with certain conditions

- Unless UI_MODE_WATCH, the assumption of app developers has been that the
 rectangular logical display will be used, without any part of it being
 obscured (except for the notch). However since 2017 there are devices
 that have been launched with rounded-corners, this is to institutionalize
 the rules for such device implementations so that the rounded corners
 would not obstruct the touch target
 (https://material.io/design/layout/density.html#touch-click-targets)
- Ensure the consistent behavior for devices with UI normal mode.
