CP-53658: Claim memory on a single NUMA node (#6369)

This PR allows xenopsd to launch domains that are using memory allocated
in a single NUMA node in a reliable way. (when restarting a VM in a host
with most of the memory in use)

Since this is only supported by Xen with this patchqueue:
https://lists.xen.org/archives/html/xen-devel/2025-03/msg01127.html, and
it needs support from xenguest and emu-manager, there are two commits
that revert the changes to just claim memory pages without a NUMA memory
node. These are easily revertable by patches to enable this
functionality in cutting edge builds.

Revertable patches:
-  xenctrl: Don't use numa_node in domain_claim_pages calls
- xenopsd/xc: Do not try to allocate pages to a particular NUMA node
