Kefu Chai 5a71bbbe59 cmake: refactor RocksDB related script
* rename Findrocksdb.cmake to FindRocksDB.cmake to match its name
* add RocksDB::RocksDB target to BuildRocksDB.cmake and
  FindRocksDB.cmake
* use RocksDB::RocksDB target instead of accessing its property
  directly, and do not link against its dependencies explicitly.
  let its INTERFACE_LINK_LIBRARIES do the job.
