issue: #42942
This pr includes the following changes:
1. Added checks for index checker in querycoord to generate drop index
tasks
2. Added drop index interface to querynode
3. To avoid search failure after dropping the index, the querynode
allows the use of lazy mode (warmup=disable) to load raw data even when
indexes contain raw data.
4. In segcore, loading the index no longer deletes raw data; instead, it
evicts it.
5. In expr, the index is pinned to prevent concurrent errors.

This PR supports create index for vector array (now, only for
`DataType.FLOAT_VECTOR`) and search on it.
The index type supported in this PR is `EMB_LIST_HNSW` and the metric
type is `MAX_SIM` only.
The way to use it:
```python
milvus_client = MilvusClient("xxx:19530")
schema = milvus_client.create_schema(enable_dynamic_field=True, auto_id=True)
...
struct_schema = milvus_client.create_struct_array_field_schema("struct_array_field")
...
struct_schema.add_field("struct_float_vec", DataType.ARRAY_OF_VECTOR, element_type=DataType.FLOAT_VECTOR, dim=128, max_capacity=1000)
...
schema.add_struct_array_field(struct_schema)
index_params = milvus_client.prepare_index_params()
index_params.add_index(field_name="struct_float_vec", index_type="EMB_LIST_HNSW", metric_type="MAX_SIM", index_params={"nlist": 128})
...
milvus_client.create_index(COLLECTION_NAME, schema=schema, index_params=index_params)
```
Note: This PR uses `Lims` to convey offsets of the vector array to
knowhere where vectors of multiple vector arrays are concatenated and we
need offsets to specify which vectors belong to which vector array.

Enables the compilation of SVE code for the bitset library if a C++
compiler supports it.
There are two conditions for enabling the SVE code
* a C++ compiler needs to have a `-march=armv8-a+sve`
* `arm_sve.h` header must be available
AFAIK, `gcc 7 does not support SVE`, `gcc 8` and `gcc 9` support SVE,
but have no `arm_sve.h` file, and only `gcc 10` has both.

The Out of Memory (OOM) error occurs because a handler retains the
entire ImportRecordBatch in memory. Consequently, even when child arrays
within the batch are flushed, the memory for the complete batch is not
released. We temporarily fixed by deep copying record batch in #43724.
The proposed fix is to split the RecordBatch into smaller sub-batches by
column group. These sub-batches will be transferred via CGO, then
reassembled before being written to storage using the Storage V2 API.
Thus we can achieve zero-copy and only transferring references in CGO.

When delete records are large, search pk one by one will result into
many `Pincells` call which creates lots of futures.
This patch make search pk execute in batch to reduce this cost.
Also add `GetAllChunks` API to utilize `PinAllCells` to reduce pins.

`promise->setValue(folly::Unit());` may run callbacks inline and some of
them may attempt to grab `mtx_`. So we should not call
`promise->setValue(folly::Unit());` while holding the lock.

The root cause of the issue lies in the fact that when a sealed segment
contains multiple row groups, the get_cells function may receive
unordered cids. This can result in row groups being written into
incorrect cells during data retrieval.
Previously, this issue was hard to reproduce because the old Storage V2
writer had a bug that caused it to write row groups larger than 1MB.
These large row groups could lead to uncontrolled memory usage and
eventually an OOM (Out of Memory) error. Additionally, compaction
typically produced a single large row group, which avoided the incorrect
cell-filling issue during query execution.

1. removed ERROR state from ListNode
2. CacheSlot will do reserveMemory once for all requested cells after
updating the state to LOADING, so now we transit a cell to LOADING
