[XLA][Numerics][HLO Value Tracking] Support original values during HLO and stableHLO round trip

The propagation of Shardy annotation is done at stableHLO level, by first converting the HLO module to an MLIR module before converting it back. This change preserves the HLO original value information during the roundtrip.
