Switch to capnp-es

[penalosa]

The capnp-ts dependency we use for Miniflare (and for type generation in workerd for constructing and reading the capnp format for the runtime) is blocking workerd upgrading TS versions to 5.7 (and will block Miniflare when we get around to upgrading—we're currently on 5.6). capnp-ts effectively abandoned and hasn't been touched in 4 years, so this PR switches us to use capnp-es. It's a followup to unjs/capnp-es#10.

Is mv going to work on Windows?

Generally it is better to put this stuff into a Node.js script I think

Assuming all the CI checks pass!

Why is this cast now necessary?

[penalosa]

Part of this involved upgrading TS to 5.7 from 5.6 for the Miniflare package—I can probably remove that, but it was causing some issues with capnp-es
