Drop [LegacyImplementedInBaseClass] from ChildNode IDL interface

Drop [LegacyImplementedInBaseClass] from ChildNode IDL interface

Drop [LegacyImplementedInBaseClass] from ChildNode IDL interface and move the
related API from Node to a new ChildNode class. All the callers of Node's
previousElementSibling() / nextElementSibling() were already previously updated
to use ElementTraversal instead for consistency.

LGTM.

Would it be hard to remove all [LegacyImplementedInBaseClass] ?

I grep'ed, it is mostly used in svg/ :(
It is also used in WindowMediaSource, apparently as a workaround for a generator
issue.

I'll try to take a look but I am relatively busy these days.
