Bug 1699302 part 1: Use "InProcess" version of GetCrossDocParentFrame(), when propagating invalidation up the ancestor chain, in nsIFrame.cpp. r=hiro

This patch doesn't change behavior; it's just switching us between two
functions that do the same thing. (One is literally a trivial wrapper for the
other.)

We're using the new "InProcess" version of this API as a way of annotating
callsites that have been vetted as behaving properly in out-of-process iframes.

This patch is focusing on some callsites where we've got a frame that needs a
repaint, and we're propagate that information up its ancestor chain. It's OK
for these notifications to stop when we hit the edge of of an out-of-process
iframe, because painting/compositing at that granularity is handled separately.
