[GraceJoin] Skip reading input when output is guaranteed to be empty
Adds early termination optimization for `GraceJoin`: if one side is empty and the join kind guarantees an empty result, the other side is no longer read.
Introduces two helpers:
* `ShouldSkipRightIfLeftEmpty`
* `ShouldSkipLeftIfRightEmpty`
Also adds unit tests covering all join kinds and empty input combinations.
Initial issue: <https://github.com/ydb-platform/ydb/issues/19797>
