Subject: rustdoc: simplify the codeblock tooltip

This commit moves the tooltip into example-wrap, simplifying allowing several
overly-complex things to be fixed:

* The mousover javascript can be removed, because hovering example-wrap can
  style the tooltip inside.
* The sibling selecor can be removed, because hovering the tooltip also
  hovers the wrapper, which can hover the codeblock itself.
* The relative positioning of the `<li>` tag, which was added in
  e861efd9f9ca45c1048a256812dfe8faffbb1367 to fix the positioning of the code
  tooltip, can now be removed, because example-wrap itself already has
  relative positioning.
