[iOS]hide the safearea view , when the page is fullscreen layout

[boboxiaodd]

Feature description

i use displaymode = 'float' , but iPhoneX, iPhone11, iPhone12 has safeAreaTop, i can't put the view over the safearea , so it can't fullscreen

Proposed solution

hide the safearea view , when the page is fullscreen layout maybe like this : statusBar.displaymode = 'fullscreen'

Alternative solutions

Add a integer prop like tabris.safeAreaTopHeight to control the height of safearea
