This shouldn't change behavior, but it packs the two arguments to DestroyFrom into a single thing, and makes nsIFrame::Destroy not so easy to call without a previous context. This is a prerequisite to pass aDestroyContext to various things that right now just mint one, which can cause badness, see bug 1851787 and related bugs. It's also a bit nicer to add things there if we need to in the future. Differential Revision: https://phabricator.services.mozilla.com/D187578
