Subject: [PATCH] Add DEBUG flag for rounded corner and display cutout path

There wasn't a good approach for engineers to distignlish bounds between
H/W display component and S/W anti-aliasing.

Allow enable color to review the anti-aliasing effect.

Test: adb root; adb shell setprop debug.screenshot_rounded_corners true;
Test: adb shell pidof com.android.systemui|xargs -i adb shell kill -9 {}
Test: check visual following above steps
Test: atest SystemUITests
Test: atest ScreenDecorationsTest
Bug: 149721168
