For derived mesh triangulation information, currently the three face corner indices are stored in the same struct as index of the mesh polygon the triangle is part of. While those pieces of information are often used together, they often aren't, and combining them prevents the indices from being used with generic utilities. It also means that 1/3 more memory has to be written when recalculating the triangulation after deforming the mesh, and that the entire triangle data has to be read when only the polygon indices are needed. This commit splits the polygon index into a separate cache on `Mesh`. The triangulation data isn't saved to files, so this doesn't affect .blend files at all. In a simple test deforming a mesh with geometry nodes, the time used to recalculate the triangulation reduced from 2.0 ms to 1.6 ms, increasing overall FPS from 14.6 to 15.
