(iOS) fixing problem status bar frame too narrow

this approach considers the safe area insets

Platforms affected

iOS

Motivation and Context

This change prevents from hardcoding the status bar frame size.
It doesn't really fix any open issue as far as I could see.

Description

the status bar frame was too narrow so that some symbols of the iPhone XR statusbar weren't
contained by the frame fully.

Testing

tested it in iPhone 8 and iPhone XR simulators

The CI failure was unrelated, I've restarted the affected build and now it's green.
