Extend `flag.pf2e.origin` to in-line tags

[MrVauxs]

When using things like Kobold Breath or Dragons Breath, or honestly any action that requires rolls or template placement, it would be great if the rolls and templates originating from these would also have the origin flag added to them. This would allow for pretty much all parts of the game to be easily referenceable, able to see what belongs to who and what.

Could also have the tags have an optional property describing what they do. Like 1d4 recharge and 2d6 damage roll.
