Make views explicitly layer-backed on macOS Mojave. (#685)

On Mojave, views automatically become layer-backed shortly after being added to
a window. Changing the layer-backedness of a view breaks the association
between the view and its associated OpenGL context. To work around this, on
Mojave we explicitly make the view layer-backed up front so that AppKit doesn't
do it itself and break the association with its context.

This was breaking the `window` example in `glutin`.
