Remove 11 heavy includes from Document.h that were only needed for pointer/reference types (already forward-declared in Forward.h), and extract the nested ViewportClient interface to a standalone header. This reduces Document.h's recompilation cascade from ~1228 files to ~717 files (42% reduction). Headers like BrowsingContext.h that were previously transitively included see even larger improvements (from ~1228 down to ~73 dependents).
