Show spell and unit IDs on tooltips

Add "Show Spell IDs" and "Show Unit IDs" options alongside the existing
item-ID line. Spell IDs come from GameTooltip:GetSpell() on spell
tooltips and from the aura's spellId on unit-aura tooltips; unit IDs
come from C_CreatureInfo.GetCreatureID on the mouseover unit's GUID
(skipped for players and guarded when the GUID carries no entry).
