Add the ability to pass long lists of inputs to 'gn refs'.

This patch adds the ability to pass a "response file"-style argument
to gn refs, so that we can pass a long list of inputs in without needing
to worry about command line lengths. This will help ensure that
we can implement 'analyze' properly for even very large patches without
needing to call 'gn refs' multiple times.
