manifests: Move GPU firmwares & kdump tools to EL10 shared manifest

Move packages to an Enterprise Linux 10 only manifest to prepare
for the package split changes:
- GPU firmwares are split into their own package in CentOS Stream 10
- kdump tools are split between kexec-utils, makedumpfile and
  kdump-utils
