Bug 996796 patch 2 - Change the public API to updating main-thread-suppressed animation styles (miniflush) in preparation for refactoring how it works. r=birtles

Later patches will combine the coalescing of restyling between the
miniflush performed for animations and for transitions into a single
RestyleTracker, which will coalesce the work better.  This patch changes
the API exposed for doing that so that the coalescing patch will contain
only the internals.
