Subject: Fixes for optical bounds feature.

1. Make the feature opt-in (ViewGroup::layoutMode defaults to CLIP_BOUNDS) without inheritance.
2. Rename COMPONENT_BOUNDS to CLIP_BOUNDS.
3. Rename LAYOUT_BOUNDS to OPTICAL_BOUNDS.
4. Complete GridLayout implementation.
5. Change the default_gap between components to 8dp, to align with the Style Guide.
