Dockerfile: Stabilize build cache for COPY command, between different machines

Dockerfile: Remote build cache optimization for COPY (on Windows)

With Docker (especially with Buildkit) you have the ability to share your images as build cache for other computers.

When running the following docker build command, Buildkit will download cache information from the images, referenced with --cache-from.

export IMAGE="my-registry.example.com/myproject/myapp:feature-1234"
export IMAGE_LATEST="my-registry.example.com/myproject/myapp:latest"
export DOCKER_BUILDKIT=1
