Default to building wxOSX, not wxiOS, under Apple ARM platforms

Now that desktop Macs using ARM exist, we should default to building the
normal, macOS-targeting, port on them and not wxiOS any more.

This is a backwards incompatible change, but it shouldn't affect many
people, so should hopefully be fine.
