fix: monitor work_area on macOS (#13309)

macOS uses a different coordinate system for visibleFrame, so to get accurate values we should only get the diff between frame() and visibleFrame() and apply that to the standard monitor position returned by CGDisplayBounds. Size isn't impacted by this, and properly returns the value (accounting for dock position).
