[Windows] Fix signed/unsigned int comparison (#142341)
Previously, we were comparing the signed int `target_length` (returned by WideCharToMultiByte) to a size_t string length, resulting in a signed/unsigned comparison warning as follows:

```
windows\runner\utils.cpp(54,43): warning C4018:  '>': signed/unsigned mismatch
```

WideCharToMultiByte returns:
* 0 on error
* the number of bytes written to the buffer pointed to by its fifth parameter, lpMultiByteStr, on success.

As a result it's safe to store the return value in an unsigned int, which eliminates the warning.

No changes to tests since this is dependent on end-user project settings/modifications and does not trigger a warning with default project settings.

Example of embedding Flutter using FlutterView

This project demonstrates how to embed Flutter within an iOS or Android application. On iOS, the iOS and Flutter components are built with Xcode. On Android, the Android and Flutter components are built with Android Studio or Gradle.

You can read more about accessing platform and third-party services in Flutter.

iOS

You can open ios/Runner.xcworkspace in Xcode and build the project as usual.

Android

You can open android/ in Android Studio and build the project as usual.
