Review Comment:
   Hmm, yes it will be converted to `ApplyFunctionExpression` etc. But in V2 
write path, these partition transforms will be used in 
`RepartitionByExpression`, and then converted into `ShuffleExchangeExec` during 
physical planning, right? 
   
   Checking the code path, the `ApplyFunctionExpression` / `Invoke` / 
`StaticInvoke`, etc, will be passed to `RepartitionByExpression` first, as 
field `partitionExpressions`, and then be passed to `HashPartitioning`, 
`RangePartitioning` etc, in `HasPartitionExpressions`, and eventually be used 
in places like `HashPartitioning.partitionIdExpression` where the computation 
of partition ID I mentioned above happened.
