Use official rust image and clean up Dockerfiles (#2804)

* Add docker/Dockerfile.multiarch

* Update normal Dockerfile to be similar to multiarch one

* docker build run on x86 and arm64 now
manifest not needed, its handled by buildx plugin

* Rename Dockerfile.arm To Dockerfile.debian

* Emulate builder on arm target too

* fix misspell

* Improve Dockerfiles

* naming

* undo multiarchbuild settings as its blocked by a dependeny, see #2806

* Delete Dockerfile.debian

.woodpecker.yml
