[NFC][SPIRV] Misc code cleanup in SPIRV Target
- Use static instead of anonymous namespace for file local functions. - Enclose file-local classes in anonymous namespace. - Eliminate `llvm::` qualifier when file has `using namespace llvm`. - Eliminate namespace surrounding entire code in SPIRVConvergenceRegionAnalysis.cpp file. - Eliminate call to `initializeSPIRVStructurizerPass` from the pass constructor (#111767)
