[bazel] Add skia_app_container macro
Add the skia_app_container macro and supporting scripts. This
will be used to build and push Docker containers to GCS. Also
add `get_workspace_status.sh` script for use by the
`--workspace_status_command` (1) argument. This creates Bazel Make
variables which can be used by various build rules. This
is used by skia_app_container.
Building container images in Skia is being added to simplify
the creation of Docker images which need Skia components (e.g.
CanvasKit). These upcoming build tasks will download a base
image (without needed Skia bits), insert the Skia component(s),
and then upload the final image.

of the generated pushk_ rule and adding copyright notices.
