Rewrite paper-progress as paper-linear-progress

This commit introduces a complete rewrite of `paper-progress` into a new
`paper-linear-progress` element. Features include the following:

- New semantics regarding `secondary-progress` which now becomes
  `buffer-value`, as it's meant to be within the spec.
- Removal of `IronRangeBehavior`, since the linear progress element is not an
  interactive UI element, nor does it have anything to do with
  representing a range as the "range"-based input elements connote.
- Slimmed down custom property API which exposes only the facets of the
  element meant to be modifiable in terms of the spec.
- Implementation of indeterminate animation which adheres to spec.
- Support for reversing the element, including all its
  transition/animations.
- Support for a buffering state.
- Complete and comprehensive test suite which adds full code coverage to
  the component.
- Revamped demo page which shows all possible functionality of the
  element.
