Hui Xiao 985c8741ad Conditionally declare and define variable that is unused in LITE mode (#9854)
Summary:
Context:
As mentioned in https://github.com/facebook/rocksdb/issues/9701, we have the following in LITE=1 make static_lib for v7.0.2
```
  CC       file/sequence_file_reader.o
  CC       file/sst_file_manager_impl.o
  CC       file/writable_file_writer.o
In file included from file/writable_file_writer.cc:10:
./file/writable_file_writer.h:163:15: error: private field 'temperature_' is not used [-Werror,-Wunused-private-field]
  Temperature temperature_;
              ^
1 error generated.
make: *** [file/writable_file_writer.o] Error 1
```

 as titled

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9854

Test Plan:
- Local `LITE=1 make static_lib` reveals the same error and error is gone after this fix
- CI

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage

CircleCI Status TravisCI Status Appveyor Build status PPC64le Build Status

RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)

This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.

Start with example usage here: https://github.com/facebook/rocksdb/tree/main/examples

See the github wiki for more explanation.

The public interface is in include/. Callers should not include or rely on the details of any other header files in this package. Those internal APIs may be changed without warning.

Questions and discussions are welcome on the RocksDB Developers Public Facebook group and email list on Google Groups.
