Add transform matrix to InputWindowHandle.

Added the transform matrix from WindowInfo native to the Java side
InputWindowHandle. This is to allow clients that register a
WindowInfoListener to translate the window's screen coordinates to
window space.

Test: Transform is now sent to WindowInfoListener
