Add the core grid layout computation and integrate it into the layout
dispatcher.

Includes:

  • AutoPlacement.h: auto-placement algorithm for grid items
  • GridLayout.h/cpp: grid layout entry point
  • TrackSizing.h: track sizing algorithm
  • CalculateLayout.cpp: grid dispatch block and #include
  • CMakeLists.txt: add algorithm/grid/*.cpp glob
  • React Native mirror of all C++ changes

Differential Revision: D93946253

Summary:
Add the foundational data types, enums, style properties, and C API for
expressing CSS Grid layouts in Yoga.

Includes:
- Grid style types (GridLine.h, GridTrack.h, GridTrackType.h)
- Updated enums (Display::Grid, Align::Start/End, Justify::Auto/Stretch/Start/End)
- Grid event (LayoutPassReason::kGridLayout)
- Style property accessors and member variables
- Public C API (YGGridTrackList.h/cpp, YGNodeStyle grid setters/getters)
- Layout helpers updated for new enum values (Align.h, AbsoluteLayout.cpp,
  CalculateLayout.cpp/h partial)
- Node.h: relativePosition made public
- React Native mirror of all C++ changes
