refactor: builders

[didinele]

Please describe the changes this PR makes and why it should be merged: Closes #8015

Change list/resolution points:

• [x] remove @discordjs/formatters re-export (deprecated currently)
• [x] remove SelectMenuBuilder and SelectMenuOptionBuilder aliases (deprecated currently, left-over from before we had different types of select menus)
• [ ] all builders now store data inside of a data field
• [x] EmbedBuilder no longer takes in camalCase options
• [x] EmbedBuilder now has "nested builders" implemented for things like the author and footer
• [x] removed API-deprecated features such as .setDMPermission
• [ ] ActionRowBuilder now has specialized [add/set]X methods as opposed to the current [add/set]Components
• [ ] validation no longer occurs during the actual "build process", but only during conversion to API data (done strictly with toJSON())
• [ ] all builders now use structuredClone
• [ ] introduced explicit clearX() methods as opposed to taking previously inconsistent null or undefined to clear

Note that this list is not final and will continue to grow.
