A few images were broken with respect to aarch64. We should now
be able to run push-all-images with ARCH=aarch64 as part of the
regular continuous integration builds, and add aarch64 smoke tests
(via user emulation for now) to the regular test suite (future).

Recursive make is difficult to follow and debug. Drop this by using
internal functions, which, while difficult, are easier than trying to
following recursive invokations.
Further simplify the Makefile by collapsing the image bits and removing
the tools/vm directory, which is effectively unused.
Fixes #4952

Using "--no-cache-dir" flag in pip install ,make sure dowloaded packages
by pip don't cached on system . This is a best practise which make sure
to fetch ftom repo instead of using local cached one . Further , in case
of Docker Containers , by restricing caching , we can reduce image size.
In term of stats , it depends upon the number of python packages
multiplied by their respective size . e.g for heavy packages with a lot
of dependencies it reduce a lot by don't caching pip packages.
Further , more detail information can be found at

For some reason these tests were broken when run via the bazel docker
container. The mechanism used was a bit crazy (self-extracting bundle),
so convert them to use straight-forward starlark rules. This has the
added advantaged that they are now independent tests.

This adapts the merged website repository to use the image and bazel
build framework. It explicitly avoids the container_image rules provided
by bazel, opting instead to build with direct docker commands when
necessary.
The relevant build commands are incorporated into the top-level
Makefile.

This change moves all Docker images to a standard location, and abstracts the
build process so that they can be maintained in an automated fashion. This also
allows the images to be architecture-independent.
All images will now be referred to by the test framework via the canonical
`gvisor.dev/images/<name>`, where `<name>` is a function of the path within the
source tree.
In a subsequent change, continuous integration will be added so that the images
will always be correct and available locally.
In the end, using `bazel` for Docker containers is simply not possible. Given
that we already have the need to use `make` with the base container (for
Docker), we extend this approach to get more flexibility.
This change also adds a self-documenting and powerful Makefile that is intended
to replace the collection of scripts in scripts. Canonical (self-documenting)
targets can be added here for targets that understand which images need to be
loaded and/or built.
