Cycles: Do more user-friendly indication that GPU devices are not found

Cycles: Disable OpenCL on macOS

This is unfortunate, but the number of bugs in this configuration
keeps growing, and almost all of them are caused by bug in OpenCL
compiler.

The compiler is not likely to be fixed, since Apple declared OpenCL
deprecated.

This evil commit is aimed to keep officially supported features
of Blender in a good working and stable state.

GP: Refactor coordinates to float

See: D4030

Partial fix to T58917 - No valid cage

The fix itself simply is to store the cage object as a pointer instead
of a string/name.

That said baking with or without cage is yielding very different results
than in 2.7.

Fix T57640: UV unwrap packing not working without sync selection.

Depsgraph: Cleanup, line length
