This patch reorder the lexical block for the translation unit, visible update block for the TU and the viisble upaete block for the extern C context after the type decl offsets block. This should be a NFC patch. This is helpful for later optimizations for eliding unreachable declarations in the global module fragment. See the comments in https://github.com/llvm/llvm-project/pull/76930. Simply, if we want to get the reachable sets of declaratins during the writing process, we need to write the file-level context later than the process of writing declarations (which is the main process to determine the reachable set).
