fixing ios_driver atoms build target, removing the ones that don't work anymore and aren't being used in that project
fixing up the ios_driver target completely

Delete deprecated methods.
Delete unused classes.
There's no apparent reason that the response for a WebDriverHandler-based
command must be rendered in a separate thread than that which executed
the command, so removing this extra complexity. If there was a reason

Remove an unnecessary level of inheritance.
Delete an unused build rule (the classes for this rule were deleted in revision e38abc6e83c75235c6d)
