Update raw-window-handle to 0.6, core-graphics to 0.23, and cocoa to 0.25

[Nopey]

These are the latest versions of each crate.

0.6 of raw-window-handle also exposes new traits which should be supported as well. The best way to do this would probably be to expose a feature which controls which versions of raw-window-handle are supported like winit does.

Split sm-raw-window-handle feature into sm-raw-window-handle-06 and sm-raw-window-handle-05 feature, with the latter's functions all being suffixed by raw_window_handle_05; these two features are not mutually exclusive.

sm-raw-window-handle-06 is a default feature.

[mrobinson]

Sincere apologies for the delay in reviewing! This look good in theory with one significant change. Let's not use the deprecated types in the new version of raw-window-handle and that way we can avoid the oddly named _05 functions in the public API (which aren't very future proof).

[mrobinson]

Thanks. This looks great. I just have some suggestions around documentation consistency and correctness.

[mrobinson]

Looks like there are some build failures on various platforms. These will need to be fixed before landing.

[Nopey]

Thanks for fixing the workflow yml; I was able to clear those compiler errors up after running CI a few times.

[mrobinson]

Thanks for all your hard work here @Nopey! I'll send this to the MQ.
