Daniel Holbert 44e8639444 Bug 1321387 part 6: Add #includes & forward declarations to some headers in layout/generic, to provide types used in those files. r=TYLin ...

Notes:
 * In CSSAlignUtils.h, I'm just adding a forward-decl for a type used there.
 * RubyUtils.h needs to #include nsIFrame.h -- a forward-declare won't
   suffice -- because it makes a nsIFrame method-call ("aFrame->GetType()").
 * ScrollSnap.h uses the "Maybe" type and a unit defined in
   nsIScrollableFrame.h; hence it needs both of those headers.
