  [DebugInfo] Only call upgradeCULocals() at module level (#68965)

Loading a 2GB bitcode file, I noticed that we spend minutes just running
upgradeCULocals(). Apparently it gets invoked every time a metadata
block is loaded, which will be once at the module level and then once
per function. However, the relevant metadata only exists at the module
level, so running this upgrade per function is unnecessary.
