ARROW-11131: [Rust] Improve performance of bool_equal

[mqy]

This PR follows @jorgecarleitao 's great PR #8541, with the following changes:

1. Implemented the logic when both lhs and rhs have zero null count.
2. May fixed a possible condition testing bug in (0..len).all(|i| {...} .
   NOTE: there are other similar cases where test_struct() failed when updated in this way.
3. Added benchmarks equal_bool_512 and equal_bool_nulls_512.

Benchmark comparing to arrow master:

equal_bool_512          time:   [52.946 ns 53.075 ns 53.188 ns]                           
                        change: [-96.295% -96.285% -96.277%] (p = 0.00 < 0.05)
                        Performance has improved.
Found 7 outliers among 100 measurements (7.00%)
