Make AccessibilityManager use main queue setup (#50112)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/50112

## Rationale
Rendering can now include main -> js sync calls.

If we allow js -> main sync calls during rendering, react native can deadlock.

So, this diff moves the js -> main sync calls to "main queue module setup", which occurs before rendering.
