Better use higher-level code from common ID management when possible. Helps to de-duplicate logic, and reduces outside usages of more 'dangerous' functions. Note that we could get rid of many of those `BKE_<id_type>_add` functions now, but on the other hand several of those take extra parameters and perform additional actions, so think we can keep them all for now as 'non-standard ID specific creation functions'.
