[PATCH v2 0/5] MR4619: mshtml: EventObj improvements.

[Gabriel Ivăncescu (＠insn)]

I sent this now because it is mostly boilerplate, with some small non-invasive patches at the end. First patch is basically all stubs except forwards from IHTMLEventObj2 getters (so it doesn't break current behavior).

--
  v2: mshtml/tests: Fix VariantClear on uninitialized variable.
      mshtml: Implement `url` prop for StorageEvent objs.
      mshtml: Send proper legacy storage event with actual url.
      mshtml: Don't expose "restricted" members.
      mshtml: Expose the other IHTMLEventObj* props.
