update: fwdb from v349+i20260512+1cce to v350+i20260512+1cce, 8 microcode changes

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.
