Jialiang Tan a0ff5b143f Add num_data_blocks_compression_rejected/bypassed to TableProperties (#14551 )

Summary:
Pull Request resolved: https://github.com/facebook/rocksdb/pull/14551

Add two new per-SST TableProperties fields that track how many data blocks
were stored uncompressed:

- `num_data_blocks_compression_rejected`: blocks where compression was
  attempted but the compressed output exceeded the ratio limit set by
  `CompressionOptions::max_compressed_bytes_per_kb`.
- `num_data_blocks_compression_bypassed`: blocks where compression was
  never attempted (e.g., kNoCompression type, no compressor available).

Together with `num_data_blocks`, these give a full decomposition:
  num_data_blocks = compressed + rejected + bypassed

Previously this information was only available via global Statistics tickers
(NUMBER_BLOCK_COMPRESSION_REJECTED / BYPASSED) which aggregate across all
SSTs. Now it is persisted per-SST in the properties block and visible via
sst_dump --show_properties.
