Build CI images in parallel (#7296)

* Factor out common setup steps

* Re-order

* Split independent builds into parallel jobs

* Cache jetson builds

* Use zstd compression

* Switch from gha cache to registry cache

A CI run (four images cached with mode-max) populates the cache with 295
cache entries totalling 23.44 GB. This exceeds gha's 10GB limit, causing
trashing. Try with a registry instead.

* Enable manual CI runs
