[FEATURE] Syntax for embedding active effects into power descriptions

[ben]

Currently the system does some NLP to figure out if ongoing damage should get a draggable tag in a chat message, and encodes what to do with it when it's dragged. Maybe it would be better if we could register an HtmlEditor enricher in CONFIG.TextEditor.enrichers that could interpret a syntax to make these things more explicit and allow for things that don't work now.

Some examples where this could be handy:

• "10 ongoing poison damage (hard save ends)"
• "mega-rage lasts until the start of your next turn" (2e gamma barbarian rage)
• "Boost defenses by 2 until you are next missed" (2e gamma paladin bastion talent)
• "You gain a bonus to two chosen defenses (AC, PD, or MD) equal to the escalation die." (2e gamma bard song of self)
  • "You gain the bonus to a single chosen defense until the start of your next turn."
• "daze the target until the end of your next turn" (2e gamma gnome kin power)
• "The enemy is vulnerable to all attacks until the end of its next turn." (2e gamma bard brass miss-me)
• "until the end of the battle, you deal an additional +8 damage with melee attacks against enemies you were not engaged with at the start of your turn." (2e gamma barbarian beast aspect)
• "Deal +1d8 damage on this attack and all other melee attacks you make this battle." (2e gamma hammer of faith)

I'd argue between the on-drop duration dialog, embedded macros and embedded AEs this is as supported as it can be in 1.31.0 - weird durations like "until you are next missed" or strange conditions aren't supported, but it's not due to lacking a syntax to express them, it's because we don't have the necessary events or context and so have to rely on the human.
