Previously, the attribute accessor were defined in the `geometry_component_*.cc` files. This made sense back in the day, because this attribute API was only used through `GeometryComponent`. However, nowadays this attribute API is independent of `GeometryComponent`. E.g. one can use `mesh.attributes()` without ever creating a component. The refactor contains the following changes: * Move attribute accessors to separate files for each geometry type. E.g. from `geometry_component_mesh.cc` to `mesh_attributes.cc`. * Move implementations of e.g. `Mesh::attributes()` to `mesh.cc`. * Provide access to the `AttributeAccessorFunctions` without actually having a geometry. This will be useful to e.g. implement `attribute_is_builtin_on_component_type` without dummy components. Pull Request: https://projects.blender.org/blender/blender/pulls/130516
