This replaces the older dynamic c arrays with blender::Vector as appropriate. Many files required minimal changes and the before/after are quite similar. There's 3 remaining usages of the old machinery but those will require more involved changes and design. See #103343 Pull Request: https://projects.blender.org/blender/blender/pulls/110981
