Node::setTextContent should avoid work when nothing changes

We already had code to handle this case, which is shared
by editing as well as HTMLElement::setInnerText.

replaceChildrenWithText does the right thing to avoid
doing work when the text content hasn't changed, etc.

Set geometry dirty bits on composited layer mappings when updating squashed layers.

The lack of setting geometry dirty bits in these cases is wrong. However, at the moment it is masked by setting needs geometry dirty bits more globally upwards in the system. When that is cleaned up these targeted ones will be in place.
