Refactor FocusController::findFocusableElementRecursively

[Ryosuke Niwa]

FocusController::findFocusableElementRecursively and FocusController::nextFocusableElement/previousFocusableElement are named backwards.
The former finds a focusable element and the latter two finds a focusable element or a shadow host.

Fix this mess.

I am getting lost in all these super-long function names. The new names do seem more accurate and precise.

This would be more readable as a for loop, but I guess it’s hard to get outerScope into something visible in the loop condition.

Hopefully next round of cleanup will help.

Yeah, I thought about the same thing but I didn't want to move FocusNavigationScope out of the loop.
