octet_length() function not working for StringView columns (SQLancer) #12149
Description
Describe the bug
Native StringView support for octet_length() has been added #11858
However it's not working for StringView column inside table
See reproducer in datafusion-cli
(Compiled from latest main using cargo run, commit a58416c)
The last query should work since this function should already have StringView support

# Now we have two equivalent tables `t1` and `t1_stringview`
# The difference is physical representation for string column (StringArray and StringViewArray)
