Emilio Cobos Álvarez 52d097c513 Bug 1851868 - Refactor nsIFrame::Destroy to pass a single DestroyContext parameter. r=dholbert
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.
