Bring back gn.el for the Emacs GN mode

gn.el used to be in the chromium source tree until gn moved
elsewhere. Now it lives somewhere else,
which makes it less useful.

This is a copy of that file as of today. The file is not updated
often, and when it is, it's just to add more keywords so
nothing critical.
