Bug fix #33911

When you open a Blender window larger than a screen, Macs clip it to match the height,
but they allow the width to be more.

Problem is that this clipping happens after all window opening code. That causes
check for HiDPI mode to fail.

Now it checks it again on event GHOST_kEventWindowUpdate, which is only on startup.
