cocoa: Fix SDL_HINT_VIDEO_MAC_FULLSCREEN_SPACES=0.

This hint is documented to not just turn off fullscreen windows going into a
new Fullscreen Space, but also to make the green button on a resizeable
window's title bar do a maximize/zoom instead of make the window fullscreen.

Previously, this only did the former and not the latter (or perhaps it worked
and the defaults changed in a newer macOS, we aren't sure).

Fixes #7470.

(cherry picked from commit 50f3adec7736a5dd9223e217e46d3abc1f95d790)
