[I] Optimize performance of `ByteViewGroupValueBuilder` on batches with inlined views [datafusion]
Dandandan opened a new issue, #16330:
URL: https://github.com/apache/datafusion/issues/16330
### Is your feature request related to a problem or challenge?
Currently a large part of view performance
`do_append_val_inner`
`do_equal_to_inner`
and others
is spent rebuilding the views, checking if they can be inlined, etc..
This is wasteful if there is no data buffer, in which case we can improve the performance.
### Describe the solution you'd like
Optimize / specialize the code for only inlined view arrays (i.e. without data buffer).
### Describe alternatives you've considered
_No response_
### Additional context

@Dandandan @Rachelint I submit a PR try to experiment this to see the performance gain or loss.
