disable window pre creation for ios (#5883)

Browse Source 
# Objective

Fixes #5882 

## Solution

Per https://github.com/rust-windowing/winit/issues/1705, the root cause is "UIWindow should be created inside UIApplicationMain". Currently, there are two places to create UIWindow, one is Plugin's build function, which is not inside UIApplicationMain. Just comment it out, and it works.
