This uses mesh's runtime mutex for both `BKE_mesh_runtime_looptri_ensure` (was using its own global RW mutex before), and `BKE_mesh_wrapper_ensure_mdata` (was not protected at all before). This is more like a band-aid than a proper fix, as mentioned in the report proper fix would be for the modifier to request those data (the relevant BVHTree, which would implicitely also call the tow others) through flags, just like it does for regular CDData layers. But this is a much bigger refactor to be done outside of bugfix scope. Reviewed By: sergey Maniphest Tasks: T78285 Differential Revision: https://developer.blender.org/D8415
