[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 calling platform services from Flutter

This project demonstrates how to connect a Flutter app to platform-specific services.

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

iOS

You can use the commands flutter build and flutter run from the app's root directory to build/run the app or you can open ios/Runner.xcworkspace in Xcode and build/run the project as usual.

Android

You can use the commands flutter build and flutter run from the app's root directory to build/run the app or to build with Android Studio, open the android folder in Android Studio and build the project as usual.

Windows

You can use the commands flutter build and flutter run from the app's root directory to build/run the app or you can build once then open build\windows\platform_channel.sln in Visual Studio to build and run.
