  [libc++] Fix 64-bit file creation for Bionic and Windows

Bionic didn't add fopen64 until API 24, but there's no meaningful
distinction between them with Bionic, so just use fopen instead.

On Windows, use _chsize_s instead of _chsize. _chsize uses a 32-bit
`long` size argument, while _chsize_s uses __int64 instead.

Factor out utils::{off64_t, fopen64, ftruncate64} for use within the
create_file function.
