Xavier Deguillard 249f2b59a0 build: make it compile with @mode/win (#7406)
Summary:
While rocksdb can compile on both macOS and Linux with Buck, it couldn't be
compiled on Windows. The only way to compile it on Windows was with the CMake
build.

To keep the multi-platform complexity low, I've simply included all the Windows
bits in the TARGETS file, and added large #if blocks when not on Windows, the
same was done on the posix specific files.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/7406

Test Plan:
On my devserver:
  buck test //rocksdb/...
On Windows:
  buck build mode/win //rocksdb/src:rocksdb_lib
