net: Split sync part of UploadFileElementReader as UploadFileElementReaderSync

Add UploadFileElementReaderSync and use it from Chrome Frame.
Remove UploadDataStream::InitSync/ReadSync
Remove UploadElementReader::InitSync/ReadSync
Allow passing null callbacks for Init/Read when callers can be confident that the operation finishes synchronously.
