Layout test text dump rebaseline using Element.innerText part 1

This patch changes tests in the following directories to use
Element.innerText for text dump:

accessibility/
animations/
battery-status/
bindings/
clipboard/
compositing/
crypto/

Most of this patch is mechanical rebaseline, except:
- Some LayoutNG-specific baselines become redundant and are
  removed
- One test is turned into failure with LayoutNG flag due to
  LayoutNG innerText bug with ellipsis (crbug.com/873957).
