To resolve the issue where FP16's -0.0 is erroneously converted to NaN on XPU, this solution introduces a forced correction logic within all Half to Float8 data conversion Functors.
This logic is based on hardware bit pattern recognition, identifying the FP16 negative zero signature 0x8000, and safely converts it to the correct negative zero value, ensuring proper input for the downstream Float8 constructor.
