Files.app: make files-toggle-ripple unclickable.

Files.app: make files-toggle-ripple unclickable.

files-toggle-ripple reserves double size of its container to perform its
ripple animation. If it's clickable, it sometimes captures click event
and it's confusing for users of this element. This CL makes the layer to
perform ripple animation unclickable.

BUG=515414
TEST=manually tested as described in the issue.

PTAL. Thank you!

We didn't need to set pointer-events:none to the host. It's enough to set to the
ripple-container. I moved it with the new patchset. PTAL. Thank you!
