don't run update before window creation in winit (#10741)

# Objective

- Window size, scale and position are not correct on the first execution
of the systems
- Fixes #10407,  fixes #10642

## Solution

- Don't run `update` before we get a chance to create the window in
winit
- Finish reverting #9826 after #10389
