feat(cpus): add ENABLE_ERRATA_ALL flag

Now that all errata flags are all conveniently in a single list we can
make sweeping decisions about their values. The first use-case is to
enable all errata in TF-A. This is useful for CI runs where it is
impractical to list every single one. This should help with the long
standing issue of errata not being built or tested.

Also add missing CPUs with errata to `ENABLE_ERRATA_ALL` to enable all
errata builds in CI.
