Similar to the previous patch, there are a lot of QI from `EventTarget` to window interfaces. This patch adds them, but unfortunately, `nsPIDOMWindowInner` and `nsPIDOMWindowOuter` do not inherit `EventTarget` directly, and they are in a public header instead of their concrete classes (`nsGlobalWindowInner` and `nsGlobalWindowOuter`). So we cannot cast them in `nsPIDOMWindow.h`, and it causes it's impossible to use the macros added by the previous patch. Differential Revision: https://phabricator.services.mozilla.com/D129782
