fix(statusbar): hide status bar correctly

[GitToTheHub]

Platforms affected

Motivation and Context

Calling window.statusbar.visible = false sets the background of the statusbar transparent, but the content of the statusbar is still visible (clock, connectivity, battery and such). The webapp content fills the freed-up space, but now overlaps with the remaining statusbar content. When the user slides down from the top, nothing happens. There's no way to make the statusbar content disappear.

Description

• Hide the real Android status bar through the built-in API and allow it to be temporarily revealed by swipe. Respect the system status-bar visibility when calculating Cordova's faux status-bar inset, preserving compatibility with cordova-plugin-statusbar.
• Fixes Cordova Android 15 - Hiding the statusbar: difference between StatusBar plugin and integrated functionality #1999

Confirm that this matches the behaviour on iOS, because I'm pretty sure it only hides the background there.

The intention for apps that want to do more complex things with the status bar (such as hiding it entirely) was to use either Fullscreen preference or to use the StatusBar plugin. The built-in status bar support was just meant to cover the most common simple cases of setting a background colour and having it push down the webview or not.

I checked this with the cordova-ios master, not using cordova-plugin-statusbar and calling window.statusbar.visible = false. The status bar is completely hidden:

It would be a little bit confusing calling window.statusbar.visible = false and it would only hide the status bar background. If this was meant to just hide the background it should be called window.statusbar.backgroundVisible.

Also calling StatusBar.hide() on cordova-plugin-statusbar by using cordova-android 15.1.0 will leave a gray space at the top:

Since it's clear now that on iOS the system status bar is hidden when window.statusbar.visible = false is called, as it also now documented on cordova-ios/cordova-js-src/plugin/ios/statusbar.js`, this change here makes it equal to Android.
