Explaining some changes that I've also propagated to the other join classes below

This ensures we have a constructed cleaner before creating the native join. Previously if allocating or initializing the cleaner failed we would only close the build table.

| this.buildKeys = new Table(buildKeys.getColumns()); |

Building the table here just makes it clear that once construction succeeds, the cleaner owns the table and is responsible for closing.
| cleaner.clean(false); | ||
| cleaner.delRef(); | ||
| isClosed = true; | ||
| cleaner.clean(false); |

Checking isClosed before delRef() prevents a rejected second close from decrementing the refcount, and setting isClosed before clean() ensures the object remains closed even if cleanup throws.

Description
Closes #24144, closes #23938.
Adds Java bindings for reusable FilteredJoin, following the patterns for HashJoin/DistinctHashJoin. This enables callers to cache the build side of semi/anti joins and reuse it across probe tables through libcudf's filtered join APIs.
This also aligns some class behavior and tests across FilteredJoin, HashJoin, and DistinctHashJoin:
