This PR disables the "auto-correction highlight" feature in iOS 17.
This feature was introduced in https://github.com/flutter/flutter/pull/45354 and https://github.com/flutter/engine/pull/13959/ (CC: @LongCatIsLooong who was the original author)
I have created [a new issue](https://github.com/flutter/flutter/issues/131622) to find other approaches to re-enable this feature.
**Note that "auto-correction" itself still works, it's only the "highlight" part is disabled:**
- iOS 16 with highlight:

- iOS 17 without highlight:

## Why disable this feature?
The original PR uses `UITextInput::firstRectForRange` API for auto-correction, since Apple does not provide any other API when auto-correction should show up, so the original PR used this API as a workaround.
In iOS 17, Apple changed a few `UITextInput` behaviors:
- UIKit does not query `UITextInput::firstRectForRange` for text range of the auto-corrected word any more.
- But instead, it repeatedly queries every single character of the current word (after entering or deleting a character), regardless whether the word should be auto-corrected or not.
I have tried all other `UITextInput` APIs that takes a text range, and none are suitable for auto-correction feature. As a result, I have to disable this feature for iOS 17 for now.
