Fix windows implemetation of QLocalSocket to emit bytesWritten() signal

Have QWindowsPipeWriter emit a bytesWritten signal and have
QLocalSocket connect this to its own bytesWritten signal.

This change contains an autotest to check for the signal emission.
Previously there was no implementation to emit the signal.
