[FPGADataFlow] Add to skip data type list DataType.FLOAT32. Set maximum width supported data type instead and issue warning

[FPGADataflow] Fix InferChannelwiseLinearLayer. Correct output datatype inference from idt and parameters. Add parameter type inference. Check parameter shape. Check if retrived intializer is None (dynamic input)

[HLSCustomOp] Add paramDataType attribute for the user to control the parameter datatype and be able to visualize it once the op is infered

Added features to tlastmarker and updated the insertion transform

[HLSCustomOp] Update FMPadding_Batch. New attribute: SIMD
