The current loading process:
* When loading an index, we first download the index files into a list
of buffers, say A
* then constructing(copying) them into a vector of FieldDatas(each file
is a FieldData), say B
* assembles them together as a huge BinarySet, say C
* lastly, copy into the actual index data structure, say D
The problem:
* We can see that, after each step, we don't need the data in previous
step.
* But currently, we release the memory of A, B, C only after we have
finished constructing D
* This leads to a up to 4x peak memory usage comparing with the raw
index size, during the loading process
* This PR allows timely releasing of B after we assembled C. So after
this PR, the peak memory usage during loading will be up to 3x of the
raw index size.
I will create another PR to release A after we created B, that seems
more complicated and need more work.

this is to prevent AI from thinking of our exception throwing as a
dangerous PANIC operation that terminates the program.

In storage v2, the `lack_bin_rows` cannot be used since field id is not
column group id, which will not be matched forever.

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

after the pr merged, we can support to insert, upsert, build index,
query, search in the added field.
can only do the above operates in added field after add field request
complete, which is a sync operate.
compact will be supported in the next pr.

- Current milvus use a serialized index size(compressed) for estimate
resource for loading.
- Add a new field `MemSize` (before compressing) for index to estimate
resource.

1. support read and write null in segcore
will store valid_data(use uint8_t type to save memory) in fieldData.
2. support load null
binlog reader read and write data into column(sealed segment),
insertRecord(growing segment). In sealed segment, store valid_data
directly. In growing segment, considering prior implementation and easy
code reading, it covert uint8_t to fbvector<bool>, which may optimize in
future.
3. retrieve valid_data.
parse valid_data in search/query.
