Implement partial field update functionality for upsert operations,
supporting scalar, vector, and dynamic JSON fields without requiring all
collection fields.
Changes:
- Add queryPreExecute to retrieve existing records before upsert
- Implement UpdateFieldData function for merging data
- Add IDsChecker utility for efficient primary key lookups
- Fix JSON data creation in tests using proper map marshaling
- Add test cases for partial updates of different field types

Fixed the issue where the result err returned by append timeout was
empty when objectstorage was unavailable, causing the client to

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.

Implement robust rewatch mechanism to handle etcd connection failures
and node reconnection scenarios in DataCoord and QueryCoord, along with
heartbeat lag monitoring capabilities.
Changes include:
- Implement rewatchDataNodes/rewatchQueryNodes callbacks for etcd
reconnection scenarios
- Add idempotent rewatchNodes method to handle etcd session recovery
gracefully
- Add QueryCoordLastHeartbeatTimeStamp metric for monitoring node
heartbeat lag
- Clean up heartbeat metrics when nodes go down to prevent metric leaks

Each ColumnReader consumes ReaderProperties.BufferSize memory
independently. Therefore, the bufferSize should be divided by the number
of columns to ensure total memory usage stays within the intended limit.
