Add set_text_properties and set_layout_child tools (from #11)

Cherry-picked the 2 unique tools from PR #11:
- set_text_properties: alignment, auto-resize, decoration
- set_layout_child: sizing, grow, align_self, positioning

The other 10 tools in the PR were already covered by the
port-tools merge (73 → 75 tools).
