[iOS] Safe area reimplementation

[naithar]

Reimplements usage of safeAreaInsets for master branch and Vulkan support.
Tested with this GDScript on Panel with Panel child:

func _ready():
	var rect = DisplayServer.screen_get_usable_rect()
	var screen_size = DisplayServer.screen_get_size()
	var view_size = get_size()
	
	var aspect_y = view_size.y / screen_size.y
	var aspect_x = view_size.x / screen_size.x
	
	$Panel.set_position(Vector2(rect.position.x * aspect_x, rect.position.y * aspect_y))
	$Panel.set_size(Vector2(rect.size.x * aspect_x, rect.size.y * aspect_y))

Hey @naithar I'm trying to get this working on 3.x - what's the var view_size = get_size() about? Can't find it on 3.x.

Oh and just to make clear: self is of type Panel in your example, correct? Many thanks in advance!

This PR and example is for 4.0 only. You can try using this code for 3.x: https://gist.github.com/naithar/01fa04248956c39a06b7b061b19be83f

get_size() is ui control method: https://docs.godotengine.org/en/stable/classes/class_control.html?highlight=get_size()#class-control-property-rect-size

Ah thanks! Works like a charm <3 Now I even understand Viewports, screen resolutions, scaling, etc. ... a little bit more!
