mshtml: Throw invalid action for IE8 window prop deletion.

Browse source 
Instead of E_NOTIMPL.

We can't use the dispex's delete because it also applies to dynamic and
builtin props and it also happens too late when deleting by name (after
looking it up), where existing tests show it doesn't look up the dispid
at all.
