Subject: [PATCH] fix(config): resolve olddefconfig validation issues

ARM64: remove CONFIG_HYPERVISOR_GUEST (x86-only option), add
CONFIG_PERF_EVENTS to satisfy CGROUP_PERF dependency, add CONFIG_MD
to enable Device Mapper menu (BLK_DEV_DM, DM_THIN_PROVISIONING).

x86_64: add CONFIG_MD for Device Mapper support.

Both: remove CONFIG_CGROUP_HUGETLB (depends on HUGETLB_PAGE which is
intentionally disabled), deduplicate TMPFS/PROC_FS/SYSFS/MODULES
entries that caused olddefconfig warnings.

Validated with `make olddefconfig` on kernel 6.12.11 for both arches.
