feat: add @discordjs/formatters

[suneettipirneni]

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

This PR simply moves formatters out of builders into it's own package. This allows users who use formatters to not have to install the entirely of /builders.

Status and versioning classification:

• Code changes have been tested against the Discord API, or there are no code changes
• I know how to update typings and have done so, or typings don't need updating
• This PR changes the library's interface (methods or parameters added)
• This PR includes breaking changes (methods removed or renamed, parameters moved or removed)

The evergrowing list of packages...

^{The list goes brrr}

I have been considering a couple of things after this PR:

1. Replace some of the overloads with dynamic returns.
2. Moving sanitizers/cleaners (from mainlib) into this package.
3. Maybe sanitize all input before formatting. (@favna and I once discussed removing formatters from Sapphire, but he told me he won't unless Discord.js's formatters sanitize their input like Sapphire does).
