kjellander 1c3548c67c Reland of iOS: Use JSON for GN configuration instead of MB + remove symbols 
Reason for revert:
MB is now updated to handle spaces in the buildername properly, something that
only affected our commit bots (not trybots).

Original issue's description:
> Revert of iOS: Use JSON for GN configuration instead of MB + remove symbols (patchset #4 id:80001 of https://codereview.webrtc.org/2688103002/ )
>
> Reason for revert:
> Something is different from trybots vs the commit bots, causing it to fail when running GN:
> https://build.chromium.org/p/client.webrtc/builders/iOS32%20Release/builds/10151
>
> Original issue's description:
> > iOS: Use JSON for GN configuration instead of MB + remove symbols.
> >
> > This aligns with how the ios recipe module is used in Chromium.
> > It should prevent breakages like one we had recently.
> >
> > It also means we're no longer setting symbol_level=1 explicitly.
> > The default is 0 (no symbols), which is now what's being used.
> >
> > Also move all the directories containing JSON files into
> > tools-webrtc/ios/bots to make it clearer (and more similar to
> > Chromium).

MB - The Meta-Build wrapper

MB is a simple wrapper intended to provide a uniform interface to either GYP or GN, such that users and bots can call one script and not need to worry about whether a given bot is meant to use GN or GYP.

It supports two main functions:

  1. "gen" - the main gyp_chromium / gn gen invocation that generates the Ninja files needed for the build.

  2. "analyze" - the step that takes a list of modified files and a list of desired targets and reports which targets will need to be rebuilt.

We also use MB as a forcing function to collect all of the different build configurations that we actually support for Chromium builds into one place, in //tools/mb/mb_config.pyl.
