Adapt to Clang 15 trunk increase in ElabortatedType sugar ...<https://github.com/llvm/llvm-project/commit/bdc6974f92304f4ed542241b9b89ba58ba6b20aa> "[clang] Implement ElaboratedType sugaring for types written bare". For one, it caused diagnostics to now emit 'OString' instead of 'rtl::OUString' etc., which required adapting a number of tests.
