fix(redfish): collect PCIe link width from xFusion servers

Browse Source 
xFusion iBMC exposes PCIe link width in two non-standard ways:
- PCIeInterface uses "Maxlanes" (lowercase 'l') instead of "MaxLanes"
- PCIeFunction docs carry width/speed in Oem.xFusion.LinkWidth ("X8"),
  Oem.xFusion.LinkWidthAbility, Oem.xFusion.LinkSpeed, and
  Oem.xFusion.LinkSpeedAbility rather than the standard CurrentLinkWidth int

Add redfishEnrichFromOEMxFusionPCIeLink and parseXFusionLinkWidth helpers,
apply them as fallbacks in NIC and PCIeDevice enrichment paths.
