On RHEL-8, the x86_64 AMI / EC2 images used a BIOS-only partition table
layout, because the base partition table unification happened in the
past only on RHEL-9 and Fedora (inherited from RHEL-9).
To make things consistent and uniform across RHEL-8 and RHEL-9, I copied
the base partition table used by RHEL-9 AMI / EC2 images to RHEL-8. This
has a side-effect for aarch64 AMI / EC2, where the `/boot` partition
size changed from 512 MiB to 500 MiB, together with the partition GUID
to "Extended Boot Loader Partition GUID".

Add a basic support for building RHEL-8.9 and RHEL-9.3 images with
composer.
Add 8.9 and 9.3 repositories to the multitude of places where we have
them.
Generate image test manifests for 8.9 and 9.3. No functional testing is
added for 8.9 or 9.3 at this moment.
This change unblocks the RHEL Gating (since unit tests are currently
failing on 8.9 and 9.3 as on unknown distribution).
