Use a separate DEPS file to drive LTO/release builds

Instead of using emscripten-version.txt, trigger LTO builds on changes to a
separate DEPS file, DEPS.tagged-release. This change copies that over the
existing DEPS file and reruns 'gclient sync' before building. This avoids the
problem of unrelated DEPS changes racing with release DEPS changes.
