Rewrite `AssetShelfSettings::operator=` and fix `~AssetShelfSettings()` to address some memory management issues: - `memcpy` was used to copy a C++ struct, which shouldn't be done: it can cause undefined behaviour if the class has vtables or internal padding. This isn't the case here, but GCC nonetheless warns for it. - `active_catalog_path` was incorrectly freed via `MEM_delete()`; it was allocated with `BLI_strdup()`, which uses `MEM_malloc_arrayN()` and thus should be freed with `MEM_freeN()`. - Self-assignments weren't handled properly, and could cause data loss. These are now all fixed. Pull Request: https://projects.blender.org/blender/blender/pulls/143701
