Revert of DevTools: keep widgets in widget hierarchy upon hide, split attach/detach cycle from show/hide. (patchset #3 id:40001 of https://codereview.chromium.org/2157363006/ )

Reason for revert:
REverting as this broke devtools on Tip-of-tree

[17701:17701:0721/140403:ERROR:CONSOLE(266)] "Uncaught (in promise) NotFoundError: Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node.", source: chrome-devtools://devtools/bundled/ui/Widget.js (266)
