Move the CLI to its own package @tailwindcss/cli (tailwindlabs#13095)

* move `cli` to its own package `@tailwindcss/cli`

* minify builds when using `tsup`

* prefer tsup cli flag over tsup.config.ts file

* add `--clean`, to make sure `dist/` folders are cleaned before building

* make CLI esm only

* use version of `tailwindcss` instead of the version of `@tailwindcss/cli`
