feat(build): Drop prepack step & directly pack /build directory (#12656)

This is mostly an internal change, but it does change the layout of the
published package, which shouldn't affect users, unless they depend on
non-public things (which nobody should!).

With this change, we will simply pack the packages as-is without moving
any folder relativity. This means we do not need a `prepack` step
anymore.

Instead, we define which files should be included in the tarball via
`files` in the `package.json`.

Fixes #12642

There are some tiny fluctuations in the comparison table but as far as I
can tell nothing serious/bad.
