Summary: In preparation for more support for file Temperatures in BackupEngine, this change does some test refactoring: * Move DBTest2::BackupFileTemperature test to BackupEngineTest::FileTemperatures, with some updates to make it work in the new home. This test will soon be expanded for deeper backup work. * Move FileTemperatureTestFS from db_test2.cc to db_test_util.h, to support sharing because of above moved test, but split off the "no link" part to the test needing it. * Use custom FileSystems in backupable_db_test rather than custom Envs, because going through Env file interfaces doesn't support temperatures. * Fix RemapFileSystem to map DirFsyncOptions::renamed_new_name parameter to FsyncWithDirOptions, which was required because this limitation caused a crash only after moving to higher fidelity of FileSystem interface (vs. LegacyDirectoryWrapper throwing away some parameter details) * `backupable_options_` -> `engine_options_` as part of the ongoing work to get rid of the obsolete "backupable" naming.

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