[MD Bookmarks] Remove the bookmarks-sidebar element.

This CL removes the bookmarks-sidebar element in and replaces it with
a root bookmarks-folder-node. This serves to specify the recursive nature
of the sidebar, and will allow for neater recursive behaviors such as
keyboard navigation.

[MD Bookmarks] Convert bookmark list to iron-list.

This CL makes the bookmark list an iron-list in order to deal with
excessively large folders and in preparation for implementing keyboard
navigation of the bookmark list.

As is, this patch will make a single item focusable in the bookmark list
which is then changed via the up and down arrows. The focus ring is only
shown for keyboard focus events.

MD Bookmarks: Focus sidebar nodes on click without showing an outline

Previously, clicking on a node in the MD Bookmarks sidebar would select
that folder without actually focusing the element. It was necessary to
click a second time to actually give focus and allow keyboard navigation.

This CL fixes this by pulling out the code from <bookmarks-item> that
prevents outlines from showing on click into a shared behavior.
Implementing this behavior improves keyboard navigation in the sidebar
without affecting mouse-only users.
