Use AsyncTask thread-safe debug logging in LinkNativeRuntime

[Copilot]

LinkNativeRuntime executes LinkRuntime via AsyncTask.WhenAll(...), so using the obsolete Log property from that background path is unsafe. This change switches the debug log call to the AsyncTask thread-safe helper without altering behavior or message content.

• Change scope

  • Updated a single call site in src/Xamarin.Android.Build.Tasks/Tasks/LinkNativeRuntime.cs:
    • Log.LogDebugMessage(...) → LogDebugMessage(...)
  • No other logging calls or task flow were changed.

• Why this matters

  • Aligns AsyncTask usage with repository guidance for background-thread-safe logging.
  • Avoids direct use of obsolete Log property in async task execution.

• Code change

  void LinkRuntime (ITaskItem abiItem)
  {
  	string abi = abiItem.ItemSpec;
  	LogDebugMessage ($"LinkRuntime ({abi})");
  }
