[PATCH 0/4] CI: Use Fedora 35 container for Linux jobs

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

PR: https://github.com/tianocore/edk2/pull/2711

Update CI, run all Linux (aka Ubuntu-GCC5) based jobs in a custom
Fedora 35 container. The image provides gcc 11 from Fedora for all
architectures. The external dependencies for gcc have been removed
so stuart does not download them. iasl and nasm are also
included in the image, but remain as ext-dep for now (CI jobs on
Windows need those).

The Dockerfiles are here:
https://github.com/osteffenrh/edk2-build-images, but they should, of
course, then move to a repo in the Tianocore group, or something like
that. The images are built automatically via GitHub Actions and then
pushed to ghcr.io.
