Updates to WebRTC Baremetal recipe

Updates to WebRTC Baremetal recipe

* Add webrtc_perf_tests to all platforms.
* Remove libjingle_peerconnection_objc_test as it's only supposed to run
for x64 builds on Mac, and don't depend on baremetal machines.
* Reduce the code duplication in the webrtc recipe module.
* Add the webrtc-limited solution to the gclient spec since it's needed for Windows.
* Remove unused recipe modules.

BUG=346198
TEST=On a machine of each platform:

When doing more testing on Mac and Windows I discovered more things needed to be
updated.

https://codereview.chromium.org/177553005/diff/60001/scripts/slave/recipe_mod...
File scripts/slave/recipe_modules/webrtc/gclient_config.py (right):

https://codereview.chromium.org/177553005/diff/60001/scripts/slave/recipe_mod...
scripts/slave/recipe_modules/webrtc/gclient_config.py:28: s = c.solutions.add()
This was moved here since it's currently only used by the Android APK builds
(and will be if we add our Chromium WebRTC builds later on). It's just a waste
of traffic to sync these things for standalone WebRTC builds right now.

https://codereview.chromium.org/177553005/diff/60001/scripts/slave/recipe_mod...
scripts/slave/recipe_modules/webrtc/gclient_config.py:59:
s.custom_vars['root_dir'] = 'src'
Local testing on Windows showed that this is needed in order to get the deps
checked out in the right place.

lgtm, though if we're mirroring the repo, we should use the mirror `if
c.USE_MIRROR`.

Don't we mirror this in the golo?

Changed to use the mirror now and it seems to work fine.

I suspect you might want to a method like 
GoogleCodeSvnURL(c, projectname, *pieces) 
in recipe_modules/gclient/config.py instead, but let's do
that in another CL instead.

Yes we do. I updated it to use the mirror.
