Add a declaration and stub implementation for the `swprintf` function. Only enable it when `LLVM_LIBC_ENABLE_EXPERIMENTAL_ENTRYPOINTS` is specified to clarify that the implementation is not ready yet. We're singling out `swprintf` among the other wide-character formatting functions because it's used in libc++ to implement `std::to_wstring` for floating point values (https://github.com/llvm/llvm-project/blob/2a2e45257b8277ae6dbd3bce1627a9b07d1a301d/libcxx/src/string.cpp#L366), and is the last remaining piece of functionality preventing us from turning on wide character support in libc++ built against llvm-libc. Adding the stub function would allow us to test the compilation with `_LIBCPP_HAS_WIDE_CHARACTERS` enabled, and start keeping track of what tests from libc++ test suite are working / not working yet.
