MLBEDSW-11334: Refactor SupportsFusedRescale to SupportsQuantization
- SupportsFusedRescale was used to validate whether a single rescale operation could be fused onto a specific operation type.
- SupportsQuantization instead validates whether the current quantization is supported for the operation. This can be used to validate rescale-fusion to multiple connections simultaneously and enables more advanced rescale-fusing logic in GraphIR.
- Use hardware-helpers to validate data types and zero points.
