iOS: Cleanup buildbot JSON files + bump iOS version to 10.0

After https://chromium-review.googlesource.com/c/412190/
we can remove all the GYP variables. The GN args are also not used
during runhooks (only GYP_DEFINES had any effect), so they're also
removed to avoid confusion. Only use_goma=True was left since
the ios recipe module uses it to decide if Goma shall be started
on the bots.

Delete unused GN/GYP-specific JSON files for bots that are now removed.

Finally, bump iOS version 10.0 and change simulator phones to
iPhone 6s to match what Chromium uses (may help solving bugs.webrtc.org/4752)

BUG=webrtc:4752, webrtc:6323

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others. This page is maintained by the Google Chrome team.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
