This fixes a few things:

* removes includes that weren't supposed to be present
* scopes some compiler code into white_box_perftests
* makes version.h/commit and angle_common id more visible
* roll zlib to a version that passes check

This should help prevent build problems from popping up in the
downstream Chromium build. We could also potentially look at
including gn check in our CQ recipe.
