Add conversions of U8 to/from BF16 and FP8
Adds type to PadAttribute and ClampAttribute so their pad_const
and max_val/min_val can be deserialized according to type
Adds conversion functions of U8 arrays to/from BF16/FP8 values
Also, refactor and expose TosaSerializer.convertDataToUint8Vec
for converting dtype/data to uint8 list for serialization
And modify convertDataToUint8Vec to serialize bf16 values into
2 bytes each, and serialize fp8 values into single bytes each.
