The `ubuntu/x86_64_android` container is the base for running cts/vts
tests, but it is getting very large (~4GB) and takes a long time to build.
To make the base container smaller (~2.6GB), and to make it quicker to
rebuild specific components, carve out two new containers from the base
container:
1) `ubuntu/x86_64_android_tools` for any tools that can be downloaded;
2) `ubuntu/x86_64_android_binaries` for any binaries (excluding
cuttlefish) that need to be built within the aosp repo.
Also, remove the jobs that start with the prefix `use-*`. These jobs pull
containers (e.g. debian/x86_64_cuttlefish) to make files inside the
container (e.g. cuttlefish.tar.xz) available to other jobs in the pipeline
as artifacts. But these `use-*` jobs can take a long time to run
(anywhere from 3 to 20 minutes to use the cuttlefish container). Instead,
use skopeo with umoci to fetch the containers and access their files,
which is much quicker.
