The VM allows both the x86 and aarch64 builders to run tests which
require access to kernel devices that docker would prevent us
from accessing.
The VM is automatically started in the endpoint script, and the
environment is set up to execute `cargo test` binaries inside the VM.
This allows for convenient interactive usage.
The VM is also integrated into the run_tests scripts, executing tests
that do not require special privileges first, while the VM is still
booting up, then execuing the remaining tests in the VM.

TEST=These test calls pass:
./ci/builder --vm ./run_tests

This CL adds the foundation for running tests consistently
in Kokoro and locally, for both x86 and aarch64.
The crosvm_builder is similar to the original image from
docker/crosvm.Dockerfile.
The main difference is that ChromeOS dependencies are not
compiled into the container, but built at runtime.
The crosvm_aarch64_builder installs the build enviornment
to cross-compile crosvm for aarch64. The tests are run
with user-space emulation using qemu-aarch64-static.
See ci/README.md for instructions on how to use these
builders.
Tests on aarch64 cannot all be run using user-space
emulation. We will need a VM to pass all smoke tests,
this work is tracked in b/177228167.
BUG=b:177133814
TEST=Tested by running
./ci/builder bin/smoke_test
./ci/builder cargo test
./ci/aarch64_builder cargo build
./ci/aarch64_builder cargo test -p tempfile
