feat: tsdown plugin

[TheAlexLichter]

This plugin adds a plugin for tsdown.

I've reused most code from the existing tsup plugin.

Thanks Alexander! Could you maybe do the following from the packages/knip folder:

bun create-plugin --name tsdown --graceful

Or --force if that doesn't work well (and use git to restore parts). That way, we'll make sure not to forget anything.

Whoops, didn't see the scaffolding script 🙈

Ran it now!
