next: build and lint Rust TF-A for QEMU

Add the basic structure and files for Rust CI scripts. Since the config
and groups are called from public yaml files in tf-a-ci-job-configs
repo, keep the names generic.

The current tfa-next branch supports only building Qemu via the default
build and clippy make targets; hence the FVP scripts are blank until we
merge the platform port patches.
