This CL also #defines DeleteFile as DeleteFileW on Windows for all
compilation units that depend on leveldb. This definition impacts
leveldb's API (leveldb::Env::DeleteFile), and is in effect in most of
Chromium, because it is introduced by <windows.h>. After this CL, the
definition is guaranteed to be in effect everywhere, so we don't have to
reason about #include side-effects.
