Add a folders_only and subtree api to bookmark manager

Adds a new API to the experimental.bookmarkManager namespace

getSubtree(id, foldersOnly, callback)

Which returns any subtree, and if foldersOnly is true, only returns the folders.
At this point, only the bookmark tree is using the new call.

BUG=39877
