For galleries with 0 items, this would previously return an empty
jQuery collection, which caused funny rendering issues later.

Since GCN aggressively modifies this.$element, these classes
didn't survive for very long, and they weren't being used
anyway.

Instead of using ve-ce-noHighlight we can just set and maintain
this.$focusable using getFocusableNode.

Now that we don't wrap generated content nodes
UL.gallery is likely to be the root, so use an
appropriate jQuery selector.

Previously they were always inline.
MWExtensionNode is now a mixin and classes which inherit it should
now inherit MWBlockExtensionNode or MWInlineExtensionNode.
