Add atom fragments for use by marionette

To compile, take a look at the `closure_fragment` rules in
the `//javascript/webdriver/atoms/BUCK`, and then compile
it with:

`./go //javascript/webdriver/atoms:is-enabled`

Optimised versions for particular drivers can be built by
appending one of:

  * `-android`
  * `-chrome`
  * `-ie`
  * `-ios`
  * `-firefox`

eg: `./go //javascript/webdriver/atoms:is-enabled-firefox`
