Fix T95356: Crash in armature edit mode and certain condition

Blender would have crashed when renaming bone in Edit Mode, Saving, and
than selecting/deselecting.

Caused by a mistake in the 0f89bcdbeb: can not "short-circuit" the
CoW update if it was explicitly requested.

Safest for now solution seems to be to store whether the CoW component
has been explicitly tagged, so that the following configuration can be
supported:

    DEG_id_tag_update(id, ID_RECALC_GEOMETRY);
    DEG_id_tag_update(id, ID_RECALC_COPY_ON_WRITE);
