Code Review
This pull request updates pointer capture behavior in FlutterWindow to capture the pointer on any mouse button down event and adds a corresponding unit test. However, a critical bug was identified where flutter_button is calculated using button_pressed before it is updated with the current message, which can lead to incorrect button reporting. Additionally, checking flutter_button == 0 is not a reliable way to determine if all mouse buttons have been released, and using a bitmask on wparam is recommended instead.

Closes #166309.
Windows only captured mouse input for primary-button drags. As a result,
drag gestures using middle, secondary, or X buttons received a pointer
remove when leaving the client area.
Capture is now enabled for every supported mouse button and released only
after the last pressed mouse button is released.
Also tested on my universal flutter input demo: https://github.com/CodeDoctorDE/flutter-input-demo/tree/e448c2cf42981d9c8b5186a7e43d1b82a0239619.
