Remove HTMLInputElement::isTextFormControlFocusable.

It is used by InputTypes to call
HTMLTextFormControlElement::isFocusable. However HTMLInputElement doesn't
override isFocusable, and we don't have any reason to call isFocusable of the
parent class of HTMLInputElement. InputTypes can call
HTMLInputElement::isFocusable directly.

Update the includes of googleurl/ to its new location.

In the Chromium repo we are migrating from //googleurl/src to //url, which is
actually committed to trunk instead of being pulled through DEPS from a external
repo.
