fix: [cp3.0] avoid structured binding capture in OpenMP lambdas (#51549)

Cherry-pick from master
pr: #51302

issue: #51231

Use init-captures for structured-binding field IDs in OpenMP lambdas.
The 3.0 adaptation also fixes the matching JSON stats callback
introduced by the 3.0 runtime-state backport.

## Test Plan

- `/opt/homebrew/opt/llvm@18/bin/clang-format -i --style=file
internal/core/src/segcore/ChunkedSegmentSealedImpl.cpp`
- `git diff --check`
- `ninja -C cmake_build -j1 -v
src/segcore/CMakeFiles/milvus_segcore.dir/ChunkedSegmentSealedImpl.cpp.o`
