Herman van Hovell 88d8de9260 [SPARK-23581][SQL] Add interpreted unsafe projection ... ## What changes were proposed in this pull request? We currently can only create unsafe rows using code generation. This is a problem for situations in which code generation fails. There is no fallback, and as a result we cannot execute the query. This PR adds an interpreted version of `UnsafeProjection`. The implementation is modeled after `InterpretedMutableProjection`. It stores the expression results in a `GenericInternalRow`, and it then uses a conversion function to convert the `GenericInternalRow` into an `UnsafeRow`. This PR does not implement the actual code generated to interpreted fallback logic. This will be done in a follow-up. ## How was this patch tested? I am piggybacking on exiting `UnsafeProjection` tests, and I have added an interpreted version for each of these.
