Remove no longer used code

We no longer consult the selector tree to find changes,
so this code is no longer needed.

/* When checking for changes via the tree we need to know if a rule further
down the tree matched, because if so we need to add "our bit" to the
Change. For instance in a match like *.class:active we'll
get a tree that first checks :active, if that matches we continue down
to the tree, and if we get a match we add CHANGE_CLASS. However, the
end of the tree where we have a match is an ANY which doesn't actually
modify the change, so we don't know if we have a match or not. We fix
this by setting GTK_CSS_CHANGE_GOT_MATCH which lets us guarantee
that change != 0 on any match. */
