fix: arm64: collapse per-core CPU info lists to a single line

Browse Source 
Store the per-core implementer/part/arch/variant/revision lists
space-separated (no embedded newlines, which also cleans up JSON and
prometheus output) and dedup them for the human-readable display, so
homogeneous systems show e.g. "0x41" instead of repeating it per core.
