This change accomplishes a couple of things:

* Unifies Touchable and Refresh layout inkdrop behavior.
* Gets 8dp inkdrop corners for Touchable
* Removes hard-coded inkdrop sizes and insets.
* Makes the flood-fill inkdrop work with extended edges (toolbar edges).
  This was not a problem for touchable as they removed extended edges.
* Changes Refresh inkdrop size to 28dps instead of inkdrop-default 24dp.
* Uses flood-fill inkdrop for Refresh.
* Increases toolbar horizontal padding to 8dp per specs.
