ARROW-11102: [Rust][DataFusion] fmt::Debug for ScalarValue(Utf8) is always quoted
This PR changes the `fmt::Debug` implementation for `ScalarValue(Utf8)` and `ScalarValue(LargeUtf8)` so that it is possible to differentiate `Utf8("NULL")` and `Utf8(NULL)` when viewing execution plans (as the string "NULL" may be a valid value).
Closes #9074 from seddonm1/fix-debug-utf8-null
