Clean up generated_bindings.gyp
Clean up generated_bindings.gyp

This does some cleanup to GYP;
only change to build is consolidating two identical gyp-time files into one.

* Move temporary list file variables to the top, with other variables
  (keeps all these lists together, removes duplicate variables, and removes
   duplicate comments)
* Add comment lines between actions (GYP files are hard to read,
  and we're going to add more actions for caching lexer/parser)
* Fix indentation so consistent
(.gyp file formatting isn't terribly consistent or linted,
but this makes reading and edits easier)
