Lucene 9.9 upgrade

[sarthakn7]

Changes:

1. Updated codec to Lucene99 from Lucene95.
2. Updated postings formats to Lucene99 and Completion99 from Lucene90 and Completion90.
3. Make TermStates#build concurrent apache/lucene#12183 made TermStates.build() concurrent, due to which the build method now needs IndexSearcher instead of IndexReaderContext. [Backport] GITHUB-11838 Add api to allow concurrent query rewrite apache/lucene#12197 had added concurrent query rewrite and introduced rewrite(IndexSearcher), marking rewrite(IndexReader) as deprecated. I have replaced all rewrite(IndexReader) with rewrite(IndexSearcher) to keep it consistent and so that we can call TermStates.build() with IndexSearcher.
4. MultiSegmentTest has a change in assertion because the toString changed, but not sure where. It might be due to change in the rewrite.
5. Refactoring HNSW to use a new internal FlatVectorFormat apache/lucene#12729 refactored HNSW to use internal FlatVectorFormat due to which the toString is different.
6. SegmentInfo has a new hasBlocks parameter in constructor, so set it to false in BucketedTieredMergePolicyTest.
7. Removed IndexReader parameter from FilterFunction.doRewrite() since it was unused.

Example plugin test fails because the jar is not uploaded yet.
