Lei, HUANG d99734b97b perf: sparse encoder (#6809)
* perf/sparse-encoder:
 - **Update Dependencies**: Updated `criterion-plot` to version `0.5.0` and added `criterion` version `0.7.0` in `Cargo.lock`. Added `bytes` to `Cargo.toml` in `src/metric-engine`.
 - **Benchmarking**: Added a new benchmark for sparse encoding in `bench_sparse_encoding.rs` and updated `Cargo.toml` in `src/mito-codec` to include `criterion` as a dev-dependency.
 - **Sparse Encoding Enhancements**: Modified `SparsePrimaryKeyCodec` in `sparse.rs` to include new methods `encode_raw_tag_value` and `encode_internal`. Added public constants `RESERVED_COLUMN_ID_TSID` and `RESERVED_COLUMN_ID_TABLE_ID`.
 - **HTTP Server**: Made `try_decompress` function public in `prom_store.rs`.

* perf/sparse-encoder:
 Improve buffer handling in `sparse.rs`

 - Refactored buffer reservation logic to use `value_len` for clarity.
 - Optimized chunk processing by calculating `num_chunks` and `remainder` for efficient data handling.
 - Enhanced manual serialization of bytes to avoid byte-by-byte operations, improving performance.
