Make Windows bluetooth to scan all found devices for services

The service scan is split in two phases. First we discover the available
devices and then we scan each discovered device for their services.
The problem was that the Windows bluetooth backend scanned only the
device that was discovered the last and then stopped. This patch
addresses this by making the scanning logic to follow that of the
other backends (Bluez, macOS, and Android).

The change required also some adjustments to the stop() logic where
the Windows backend did not send the canceled() signal. The worker
"cancel logic" is nonexistent and does not produce the signal. A related
issue was that the stop() function is called both by
the baseclass and the windows specialization itself for slightly differing
purposes => needed to be split in two: releaseWorker() and stop().
