Re-land "Support tuning sysui_rounded_size"

Previous sysui_rounded_size only works on device w/o rounded_corner_top
or rounded_corner_bottom. Support tuning sysui_rounded_size for all
cases.

Previous landed CL: ag/17200803
Previous reverted CL: ag/17352247

Bug: 220659061

Test: atest RoundedCornerResDelegateTest ScreenDecorHwcLayerTest \
            ScreenDecorationsTest
Test: Manually check rounded corner size on normal phone, hardware-layer
      phone with 'adb shell settings put secure sysui_rounded_size XX'
