macOS: Handle window titlebar buttons independently from style mask
Style masks such as NSWindowStyleMask{Resizable,Miniaturizable} affect whether the window has a title bar button for the action, but also whether the window can be resized or minimized through other means, for example if the window border can be dragged to resize. By decoupling the visibility and enablement of the title bar buttons from the style mask we can individually control the buttons, and leave the style mask set to enable behaviors we always want. We were already doing this for the NSWindowZoomButton. Unfortunately AppKit not only checks NSWindowStyleMaskMiniaturizable during a call to miniaturize, but also whether the title bar button is enabled. To allow minimizing windows without the titlebar button we detect the situation and give AppKit a NSWindowMiniaturizeButton that we haven't disabled. The alternative would be to temporarily enable the NSWindowMiniaturizeButton during the minimize, but this results in the button flashing yellow for the duration of the animation.
