[FBcode->GH] [codemod] Remove "using namespace" dep

[NicolasHug]

Summary:
The files modified in this diff rely on using namespace in the global namespace. In this diff we break that reliance by adding appropriate namespace qualifiers.

Landing this diff helps us onboard our code to the -Wheader-hygiene warning flag.

D54681732 aggregates many of these files and D54681798 removes the associated headers; however, I have broken D54681732 up to make landing and rollbacks safer.
