Tao Zhou d382b5f666 Add a util to support querySelector with shadow DOM compatible.
This util meant to work as a polyfill for `$$` in polymer as `$$`
won't work in shadow DOM. But this util will only work when
selector is within one shadow host, won't work when selector
is crosing multiple shadow hosts.
