ARROW-10445: [Rust] Added doubleEnded iterator to PrimitiveArrayIter This puts it in line with `array::NullIter`. This PR is complementary to #8561 (which removes `NullIter`), so that the PrimitiveArrayIterator can be reversed in the same way `NullIter` can. Together with #8561, it re-allows Dictionary keys to be iterated backwards. Closes #8562 from jorgecarleitao/double_ended Authored-by: Jorge C.
