Elias Naur 0e592f8bc6 app,app/internal/wm: [macOS] refresh context on display change
The NSViewGlobalFrameDidChangeNotification notification is documented to
be fired every time [NSOpenGLContext update] needs to be called.
However, the notification fails to fire on my setup when a window is
moved to a display with a different pixel scale, which leads to
incorrectly sized output.

This change gets rid of the notification and updates the context before
every frame.
