4a84fc26 - [NFC][SPIRV] Refactor emitGlobalDI to use helpers and store CompileUnitRegMap

[NFC][SPIRV] Refactor emitGlobalDI to use helpers and store CompileUnitRegMap This commit refactors emitGlobalDI() to use the extracted helper functions and adds CompileUnitRegMap to store DebugCompilationUnit registers for later lookup by function-level debug info emission. This prepares for function-level debug info emission which needs to look up compile units.
