[PATCH v10 07/17] CI: Use Fedora 35 container (Linux only)

["Oliver Steffen" <osteffen@redhat.com>]

Run all Linux based jobs in a container, using a custom Fedora 35 image
(gcc 11). The image is hosted on ghcr.io and the Dockerfiles are
here: https://github.com/tianocore/containers
The version numbers of gcc, iasl, and nasm are pinned to avoid
unintended upgrades during image rebuild.

Do not run apt-get in CI jobs to install qemu and gcc dependencies.
Assume the container image provides these.

Use Python from the container image, do not download at runtime.
