Bug 1215406 - Part 1: Remove NS_STYLE_ANIMATION_DIRECTION_XXX and NS_…

…STYLE_ANIMATION_FILL_MODE_XXX. r=heycam

Replace the definitions of
1. NS_STYLE_ANIMATION_DIRECTION_XXX with mozilla::dom::PlaybackDirection
2. NS_STYLE_ANIMATION_FILL_MODE_XXX with mozilla::dom::FillMode

So we can static_cast mozilla::dom::PlaybackDirection and mozilla::dom::FillMode
into integers directly.
