[SPARK-37803][SQL] Add ORC read benchmarks for structs
### What changes were proposed in this pull request?
Add Orc read benchmarks for structs and nested structs.
### Why are the changes needed?
This PR will provide baseline benchmarks for PR #35090, which will
hopefully make the deserialization of Orc structs more efficient.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
New benchmark tests.
Closes #35100 from bersprockets/orc_struct_benchmark.
