Revert GN declare_args() change.

Revert GN declare_args() change.

We've seen a bunch of bug reports for flaky build failures
complaining about unused or undeclared arguments; it seems
possible that this CL might be the cause, so I'm speculatively
reverting it and we can see if things get better; reverting the
change makes GN more permissive, so this should be reasonably safe.

This reverts r433944 (f6fd4d747c77e1c7968eb5af8b195a94a7ed2fac),
i.e. https://codereview.chromium.org/2509333003. This CL leaves
the build files changes that were in that CL because they
are backwards-compatible and improvements regardless.
