[windows] add AddFontResource

[CarsonSlovoka]

Add AddFontResource on windows so that after installation, you can find the font in other applications.

gdi32dll := syscall.NewLazyDLL("Gdi32.dll")
procAddFontResource := gdi32dll.NewProc("AddFontResourceW")
filePath, _:= syscall.UTF16PtrFromString("C://.../xxx.ttf")
_, _, _ = procAddFontResource.Call(uintptr(unsafe.Pointer(filePath)))
