Add tree scope hash into MatchedPropertiesCache key

It is possible that two elements match exactly the same rules with the
exact same tree scope order numbers, but still have different
ComputedStyle because they contain different tree-scoped names and
references. MPC currently is not handling this case, causing incorrect
reusing of ComputedStyle, and therefore, tree-scoped name confusions.

This is fixed in this patch.
