iOS: Update MB and JSON configs + enable Goma

Turns out that if mb_type is missing in the JSON, GYP is run the
traditional way instead of having the MB configuration decide.
This turns on MB for those builders.
See https://codereview.chromium.org/2194703002 for how Chromium
switched from GYP->GN.

The JSON environment for GYP and GN is only used during runhooks
step since there are scripts that key on some of these environment variables.
The actual build that is compiled is defined by the MB config, which
is now updated to have component=static_library everywhere for iOS.
With this CL, all configs gets a full GYP+GN environment.

When flipping bots over to GN, the following line will need to be added
in addition to changing mb_type:
"additional_compile_targets": [ "all" ],

Goma was also enabled for all builders to reduce compile time.

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.
