docker: hardcode BUILD_ENV_IMAGE tag in COPY --from=

Browse source 
'COPY --from=${BUILD_ENV_IMAGE}' is rejected by BuildKit:
  failed to solve: failed to parse stage name "${BUILD_ENV_IMAGE}":
    invalid reference format: repository name
    (library/${BUILD_ENV_IMAGE}) must be lowercase

A COPY --from= can only reference either a local stage of the
same Dockerfile, or a static image reference. ARG interpolation
in the stage name is not supported.

Replace the ARG + interpolation with the pinned tag in all
three Dockerfile.runtime* files. Bumping the build-env image
now means updating Dockerfile, Dockerfile.backend, and the three
Dockerfile.runtime* in lockstep.
