Optimized JSON filter execution by introducing
ProcessJsonStatsChunkPos() for unified position calculation and
GetNextBatchSize() for better batch processing.
Improved JSON key generation by replacing manual path joining with
milvus::Json::pointer() and adjusted slot size calculation for JSON key
index jobs.
Updated the task slot calculation logic in calculateStatsTaskSlot() to
handle the increased resource needs of JSON key index jobs.

Issue: #41210
After https://github.com/zilliztech/tantivy/pull/5, we can provide
milvus row id directly to tantivy rather than record it in the fast
field "doc_id".
So rather than search tantivy doc id and then get milvus row id from
"doc_id", now, the searched tantivy doc id is the milvus row id,
eliminating the expensive acquiring row id phase.
The following shows a simple benchmark where insert **1M** docs where
all rows are "hello", the latency is **segcore** level, CPU is 9900K:
**The latency is 2.02 and 2.1 times respectively.**
bench mark code:
```
TEST(TextMatch, TestPerf) {
auto schema = GenTestSchema({}, true);
auto seg = CreateSealedSegment(schema, empty_index_meta);
int64_t N = 1000000;
uint64_t seed = 19190504;
auto raw_data = DataGen(schema, N, seed);
auto str_col = raw_data.raw_->mutable_fields_data()
->at(1)
.mutable_scalars()
->mutable_string_data()
->mutable_data();
for (int64_t i = 0; i < N - 1; i++) {
str_col->at(i) = "hello";
}
SealedLoadFieldData(raw_data, *seg);
seg->CreateTextIndex(FieldId(101));

It does not make any sense to create single segment tantivy index for
old version such as 2.4 by using tantivy V7.
So, clean the relevant code.

issue: https://github.com/milvus-io/milvus/issues/40006
This PR make tantivy document add by batch. Add document by batch can
greately reduce the latency of scheduling the document add operation
(call tantivy `add_document` only schdules the add operation and it
returns immediately after scheduled) , because each call involes a tokio
block_on which is relatively heavy.
Reduce scheduling part not necessarily reduces the overall latency if
the index writer threads does not process indexing quickly enough.
But if scheduling itself is pretty slow, even the index writer threads
process indexing very fast (by increasing thread number), the overall
performance can still be limited.
The following codes bench the PR (Note, the duration only counts for
scheduling without commit)
```
fn test_performance() {
let field_name = "text";
let dir = TempDir::new().unwrap();
let mut index_wrapper = IndexWriterWrapper::create_text_writer(
field_name,
dir.path().to_str().unwrap(),
"default",
"",
1,
50_000_000,
false,
TantivyIndexVersion::V7,
)
.unwrap();
let mut batch = vec![];
for i in 0..1_000_000 {
batch.push(format!("hello{:04}", i));
}
let batch_ref = batch.iter().map(|s| s.as_str()).collect::<Vec<_>>();
let now = std::time::Instant::now();
index_wrapper
.add_data_by_batch(&batch_ref, Some(0))
.unwrap();
let elapsed = now.elapsed();
println!("add_data_by_batch elapsed: {:?}", elapsed);
}
```
Latency roughly reduces from 1.4s to 558ms.

fix: https://github.com/milvus-io/milvus/issues/40823
To solve the problem in the issue, we have to support building tantivy
index with low version
for those query nodes with low tantivy version.
This PR does two things:
1. refactor codes for IndexWriterWrapper to make it concise
2. enable IndexWriterWrapper to build tantivy index by different tantivy
crate
