Add support for Apple Development certificates to Xamarin.Mac MSBuild

[wjk]

Does mostly what the title says. I also took the opportunity to update an occurrence of "OS X" to the current branding.

Please note that I was not able to change the corresponding value for the iOS platform because those constants are in the Xamarin.MacDev submodule, and if I was make the changes in a fork, I would then have problems properly reintegrating the submodule change into this repository. I have included the required changes as a diff below; if someone could apply them for me (or tell me how I should best apply them myself), I would appreciate it. Thanks!

Please note that I was not able to change the corresponding value for the iOS platform because those constants are in the Xamarin.MacDev submodule, and if I was make the changes in a fork, I would then have problems properly reintegrating the submodule change into this repository.

The way to do this is to create a fork of the Xamarin.MacDev, create a pull request with your changes, and once that pull request has been merged, update this pull request with the submodule bump.

Not quite sure about this one but as long as our tests are happy 👍
