Migrate a Windows project to support dark title bars

Migration steps

Example

Projects created before Flutter 3.7 have light title bars even
when the Windows theme is dark mode. Projects created before
Flutter 3.7 need to be migrated to support dark title bars.

Migration steps

Your project can be updated using these steps:

Verify you are on Flutter version 3.7 or newer using flutter --version

If needed, use flutter upgrade to update to the latest version of the
Flutter SDK

Backup your project, possibly using git or some other version control system

Delete the following files:
    
      windows/runner/CMakeLists.txt
      windows/runner/win32_window.cpp
      windows/runner/win32_window.h
