Singletons need some improvements (abilities must be able to have source related settings like hints)

Current situation:
1. XMage implements many keyword abilities as singleton (one object instance for all cards, example: `HasteAbility`). It's easy to use for devs and easy to search abilities in code;
2. Keyword abilities can have different settings (e.g. with or without ability description, see #6728);
3. Singleton ability can't store any card related settings (it's same for all cards);

So it can be useful to implement special mechanics for card's related settings for singleton abilities. E.g. you can enable or disable full description on specific card. Interface like `KeywordAbility` with special methods.

Potential uses:
* Hide or show keyword ability's hint/description in card;
* Find all keyword abilities in card to show it as icons (see #4488);
* Find all keyword abilities in card to show full description like MTG Arena do (shows full keyword description for all keywords in card's hint even if that card's have only simple word in printed card);
* Combine multiple keywords as one rule (example: [Bontu the Glorified](https://scryfall.com/card/akh/82/bontu-the-glorified)).
