Forward-merge triggered by push to branch-23.10 that creates a PR to keep branch-23.12 up-to-date. If this PR is unable to be immediately merged due to conflicts, it will remain open for the team to manually merge.

This PR adds the pre-filtering feature to the CAGRA search implementations.

Rel: taken over from #1765

## Algorithm
The pre-filtering algorithm removes a node that should not be in the final result after it has behaved as a parent node. This way, the nodes that should not be in the final result are also used in the graph traversal, avoiding potential performance degradation.

## Changes
- Add filtering operation on a parent node after internal top-M buffer candidate calculation.
- Add filtering operation to result buffer before storing them in the device memory.
