Reland "Implement new dialog shadow focus behavior"

This implements the new dialog initial focus behavior specified in these
changes:
https://github.com/whatwg/html/pull/7079
https://github.com/whatwg/html/pull/7284
https://github.com/whatwg/html/pull/7361
https://github.com/whatwg/html/pull/8174

The gist of the changes are:

1. Use the DOM tree instead of the flat tree to search for an element to
   give initial focus.
2. Don't traverse into shadow roots when looking for elements to give
   initial focus unless the shadow root has delegatesFocus.

This will stay experimental until I have also made the other changes for
dialog initial focus: https://github.com/whatwg/html/pull/8199
After those changes have been made as well, I will carefully enable the
flag by default.
