Cherry-pick of #61200 to branch-4.0.
### What problem does this PR solve?
Issue Number: close #DORIS-24681
`search('NOT msg:omega')` incorrectly includes NULL rows in the result set,
while `NOT search('msg:omega')` correctly excludes them.
**Root cause:** `ExcludeScorer` does not implement `has_null_bitmap()` /
`get_null_bitmap()`, inheriting the `Scorer` base class defaults that always
return `false` / `nullptr`. This caused NULL documents to be treated as TRUE
(matching) rather than NULL, violating SQL three-valued logic where `NOT(NULL)
= NULL`.
**Fix:** Enhance `ExcludeScorer` with null bitmap support:
- Accept a pre-collected `exclude_null` bitmap (read from index at O(1) cost)
- Check it during `advance()`/`seek()` before the original lazy
`is_within()` exclusion
- Implement `has_null_bitmap()`/`get_null_bitmap()` to propagate null info
- Plumb `binding_keys` from `function_search.cpp` through
OccurBooleanQueryBuilder → OccurBooleanQuery → OccurBooleanWeight for proper
null bitmap resolution
### Release note
Fix search('NOT field:value') incorrectly including NULL rows by using
null-bitmap-aware ExcludeScorer.
