chore(ci): Improve docker releases

[clabby]

Overview

Introduces a new docker release pipeline that uses docker bake to achieve cross-platform builds for all images in this repository using a single generic workflow. This streamlines the process of releasing our images, and drastically speeds up cross-platform image builds by both parallelizing builds across different runners and using arm64 native runners rather than QEMU on amd64 for arm64 builds.

Also splits up the kona-host image from the reproducible prestate image, so that we can serve it individually rather than with the prestate artifacts.
