[singlejar] Use Win32 API directly in OutputJar::AppendFile

`pread` is only used by `OutputJar::AppendFile`. Implementing `OutputJar::AppendFile` directly with Win32 API means better performance and no worry about whether `pread` polyfill follows POSIX spec correctly.

Also remove unused `pread` polyfill.

See #2241

Closes #6021.
