UBUNTU: [Config] Intel Sapphire Rapids HBM support needs CONFIG_NUMA_EMU

BugLink: https://bugs.launchpad.net/bugs/2008745
Currently Ubuntu kernel has this kernel config disabled.
But in some cases, Intel's Sapphire Rapids High Bandwith
Memory (SPR-HBM) needs this option.

Memory bandwidth has been a bottleneck of increasingly memory bound
workloads. Sapphire Rapids plus HBM is specifically targeted to
cater to these workloads, traditionally served using overprovisioning
of memory devices.
