clang-15 requires `extern "C"` to be the first attribute and does not allow mixing GNU attributes and standard attributes. Temporarily split and re-order attributes to prevent compilation errors. Avoid updating the public stdlib here (`Visibility.h`) and instead add the definitions to `Config.h`, which all impacted headers and up including. This should be removed once Swift uses at least stable/20221013, which has https://reviews.llvm.org/D137979 and would thus allow us to just move `SWIFT_RUNTIME_EXPORT` to be the first attribute. Resolves swiftlang#61468.
