Currently, CGOps.h and FIROps.h contain `using namespace mlir;`. Every file that includes one of these header files (directly and transitively) will have the MLIR namespace enabled. With name-clashes within sub-projects (LLVM and MLIR, MLIR and Flang), this is not desired. Also, it is not possible to "un-use" a namespace once it is "used". Instead, we should try to limit `using namespace` to implementation files (i.e. *.cpp). This patch removes `using namespace mlir;` from header files and adjusts other files accordingly. In header and TableGen files, extra namespace qualifier is added when referring to symbols defined in MLIR. Similar approach is adopted in source files that didn't require many changes. In files that would require a lot of changes, `using namespace mlir;` is added instead. Differential Revision: https://reviews.llvm.org/D120897
