ui/cocoa.m: Fix macOS 10.14 deprecation warnings

macOS 10.14 deprecated NSOnState/NSOffState in favour of
NSControlStateValueOn/NSControlStateValueOff. Use the new constants,
and #define them to the old ones when compiling against a pre-10.13 SDK.
Also [NSGraphicsContext graphicsPort] is now deprecated, use
[NSGraphicsContext CGContext] when available.
