AndroidHarness : support display cutouts

[vxel]

Currently the AndroidHarness does not support display cutouts (see https://developer.android.com/develop/ui/views/layout/display-cutout). This feature would allow the display to exploit the whole screen instead of leaving a margin at the notch/cutout, which is essential for a perfect immersive experience.

The AndroidHarness fullscreen option is not sufficient since it does not set the required flags. One solution would be to (add an option to) add the flag WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS.

Thanks @vxel for opening this.
