don't create windows on winit StartCause::Init event (#9684)

# Objective

- #7609 broke Android support

```
8721  8770 I event crates/bevy_winit/src/system.rs:55:  Creating new window "App" (0v0)
8721  8769 I RustStdoutStderr: thread '<unnamed>' panicked at 'Cannot get the native window, it's null and will always be null before Event::Resumed and after Event::Suspended. Make sure you only call this function between those events.', winit-0.28.6/src/platform_impl/android/mod.rs:1058:13
```
## Solution

- Don't create windows on `StartCause::Init` as it's too early
