Add a 'configs_exclude' option to the generated GN 'create_tests' template.
Chromium uses GN's default configs feature which makes all targets default to a
set of configs. It then expects third_party code to take one of them
(chromium_code) out and put in a different one (no_chromium_code).
Because of that, we need a way to tell the template to emit -= lines. Add a
separate option for that.
(It may be worth making us clean against the chromium_code config rather than
the no_chromium_code one, but I'll explore that separately in case making the C
code clean ends up being a rabbithole.)
