Rename the `__tuple` directory in libc++ headers to `__tuple_dir` to avoid file collision when installing. Historically, `__tuple` has been a file and it has been replaced by a directory in 2d52c6bfae801b016dd3627b8c0e7c4a99405549. Replacing a regular file with a directory (or more importantly, the other way around when downgrading) is not universally supported. Since this is an internal header, its actual name should not matter, so just rename it to avoid problems. Differential Revision: https://reviews.llvm.org/D139270
