fix(select): use native after option for pagination on Tarantool 2.10+

Optimize crud.select() and crud.pairs() pagination with after cursor
by using native after option on Tarantool 2.10+ for O(1) cursor
positioning instead of O(N) scroll_to_after_tuple.

The optimization applies to all iterators (GT/GE/LT/LE/EQ/REQ).
For EQ/REQ iterators, native after is used only when after_tuple
key matches scan_value to avoid 'Iterator position is invalid' error.

Readview operations use native after only on Tarantool 3.x, since
the after option for read_view:pairs() is not available in 2.x.

Closes #488
