Description
Fix a bug in TE integration.
Currently we only override te.cpp_extensions.cast_to_fp8 with our own cat_to_fp8 in msamp.te.extension.
We also need to override te.module.linear.cast_to_fp8. Otherwise, it will use the original function which does not support ScalingTensor and will raise an exception in Megatron-LM
