DynamicTablesPkg: AcpiSsdtPcieLibArm : Add UID to slot creation
Expose the UID value to GeneratePciSlots().
This is needed for some cases for example:
https://docs.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports#identifying-externally-exposed-pcie-root-ports
Name (_DSD, Package () {
ToUUID("EFCC06CC-73AC-4BC3-BFF0-76143807C389"),
Package () {
Package (2) {"ExternalFacingPort", 1},
Package (2) {"UID", 0},
}
})
