  Reland "[clang][modules] Move `UNHASHED_CONTROL_BLOCK` up in the AST file"

This reverts commit b6ba804f7775f89f230ee1e62526a2f8225c7966, effectively relanding commit 7d1565727dad3acb54fe76a908630843835d7bc8.

The original commit incorrectly called `ASTWriter::writeUnhashedControlBlock()` before `ASTWriter::collectNonAffectingInputFiles()`, causing SourceLocations/FileIDs in the pragma diagnostic mappings block to be invalid. This is now tested by `clang/test/Modules/diag-mappings-affecting.c`.
