Motivation and Context

I noticed running snapshot on some older iPhone and iPad models that they were missing. I worked out the list of supported devices for the report is hardcoded, so have updated the list of devices.

Description

Added missing older iPhone simulator names to the definitions used to output generated HTML files.

Also reordered the iPads and Apple Watches to that the all ascend from oldest to newest, in the same order as the iPhone models are listed.

Thanks for the PR, @kylehowells! I don't think there will be any issues, but to be on the safe side can you login to CircleCI using GitHub OAuth so the tests run on your PR?
