Goal

• RHEL 10 will support only x86_64-v3 and higher CPUs [0]. The upgrade tooling has to check if used CPU is compatible and inhibit upgrade if in case it is not.
• Unfortunately, there is no simple hardware search that can be performed to identify -v1 and -v2 CPUs. The only way to do this is to look at the CPU flags and determine whether the CPU has the appropriate flags[1]
• It's difficult to reflect the x86-64-v1/2 support state into the hardware-removal-support.yaml [2]
• darcari has a bash script[3] that reports the support level of a CPU - can be used as an inspiration

Acceptance Criteria

• leapp 9 to 10 upgrade on x86_64-v2 CPU is inhibited with proper message
• leapp 9 to 10 upgrade on x86_64-v3 CPU proceeds

Update(pstodulk):

• Note that original exceptence criteries contained requirement to inhibit the upgrade for x86_64-v1 intel microarch when upgrading RHEL 9 -> 10, however that's not possible as RHEL 9 does not support x86_64-v1 microarch - it's not possible to install it on such a machine. So I drop it.
