mtklein f037d48e29 GN: refactor third_party/gni
This fixes the build on Linux (dep on third_party:zlib -> third_party/zlib).

  I've moved declare_args() {} back to each .gn file... seems like args want
  to be as local as possible in GN land.

  Additionally, refactor all the common third_party config and warning flag
  changes into a template, third_party.  This lets it all live together in a
  .gni: at head unwanted_configs can be in a .gni (it's just a variable) but
  config("no_warnings") (and thus third_party_configs) cannot, as configs
  cannot be part of .gni files.
