BKE_main: Relations: Add `TO`/`FROM` variants of processed flags.

In some cases, it can be usefull to distinguish when an entry has been
processed in which direction (`to` when handling ID pointers used by
the entry, `from` when handling ID using this entry).

Previous `MAINIDRELATIONS_ENTRY_TAGS_PROCESSED` tag is now a combination
of the two new ones.
