Yanqin Jin 0376869f05 Remove using namespace (#9369)
Summary:
As title.
This is part of an fb-internal task.
First, remove all `using namespace` statements if applicable.
Next, utilize multiple build platforms and see if anything is broken.
Should anything become broken, fix the compilation errors with as little extra change as possible.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9369

Test Plan:
internal build and make check
make clean && make static_lib && cd examples && make all
