JC Grünhage e2411818ef Add SBOMs and provenance attestations to container images (#12768)
## Problem
Given a container image it is difficult to figure out dependencies and
doesn't work automatically.

## Summary of changes
- Build all rust binaries with `cargo auditable`, to allow sbom scanners
to find it's dependencies.
- Adjust `attests` for `docker/build-push-action`, so that buildkit
creates sbom and provenance attestations.
- Dropping `--locked` for `rustfilt`, because `rustfilt` can't build
with locked dependencies[^5]

## Further details
Building with `cargo auditable`[^1] embeds a dependency list into Linux,
Windows, MacOS and WebAssembly artifacts. A bunch of tools support
discovering dependencies from this, among them `syft`[^2], which is used
by the BuildKit Syft scanner[^3] plugin. This BuildKit plugin is the
default[^4] used in docker for generating sbom attestations, but we're
making that default explicit by referencing the container image.
