1. Uses the all-dependencies image as the base image.
2. Has all compilers use Ubuntu 24.04.
Notes: This change implitly changes our supported compilers to GCC v10
to v13 and Clang v14 to v18. This will be fully incorporated into the
project later.

The compiler tests are failing to to a compile bug in Clang 7:
https://github.com/gem5/gem5/actions/runs/10170081794
Given Ubuntu 20.04 APT installs v10 by default (i.e., with `apt install
clang`). This is the oldest LTS Ubuntu version. It therefore seems
sensible to drop support for older (<v10) versions of clang.

We only test the latest LTS Ubuntu release with min-deps. With 24.04, we
no longer require the 22.04 min dependencies image.

Speciftying a DevContainer in gem5 allows for users to quickly create an
environment in which they can develop, build, and run gem5. The
".devcontainer/devcontainer.json" file specifies the properties of the
container. In this commit they are as follows:
1. The Docker image ghcr.io/gem5/devcontainer. This is built from
"util/dockerfiles/devcontainer". This Dockerfile provides all
dependencies and a pre-built gem5 binary from the current main branch
(added to "/usr/local/bin"). In order to support this Docker container
on different platforms we use the Docker multi-platform feature. As
such, this must be built using `docker buildx bake devcontainer --push`
which reads the `docker-bake.hcl file for the specification of the
multi-platform image.
2. Visual Studio extensions. This is a list of Visual Studio Code
extensions useful when developing gem5. They are automatically added the
Visual Studio dev container.
3. Features. Features are enhancemets that can be added to a
DevContainer. Normally they are libraries and other commonly used tools
to be included in the Container. As we have our dependencies specified
in the Dockerfile here we select one to enable Docker inside the
container, one to enable the Github CLI, one to improve Linting, and
finally one to enable the vscode CLI.
4. The On Create Command : This command allows us to specify commands to
be run after the DevContainer is created. In this case we execute
".devcontainer/on-create.sh" which, right now, refreshes the git index
and installed the pre-commit checks.
Introduced in https://github.com/gem5/gem5/pull/236 the
"docker-build.yaml" file will allow us to build and push docker images
to the GitHub Container Registry. This allows for both automation of
docker image building and allows us to utilize Github's zero-cost
pulling policy for downloads to GitHub Actions runners.
In this PR https://github.com/gem5/gem5/pull/236 has been altered to
use Docker `buildx` which allows for multi-platform Docker Image builds.
A multi-platform Docker image pull automatically pull the correct image
for your platform from a single URL. In this prototype the images are
build to both `linux/arm64` and `linux/amd64` have been set.
Docker `buildx` has it's own file format for specifying image builds
called `bake`. "util/dockerfiles/docker-bake.hcl" has been added with
the goal of replacing "util/dockerfiles/docker-compose.yaml".
In this proof-of-concept doesn't build all our docker images, just
enough to ensure it works inside our actions as intended.
