Moves the feedback panel JS files out of the main script bundle, into
the lazily loaded set used for Polymer elements.

Also inline the background image resources for the button for now: we
will replace them in future CL with a cr-icon-button. Remove the icon
pause/expand/cancel SVG images: no longer used.
