WindowsAudio: improve supported formats detection.

Browse Source 
QAudioDeviceInfo::isFormatSupported() now tries to open the device with
that format to theck if it is supported. We were before simply checking
that its parameters were included in the list of supported values,
which might be incomplete.

In addition, since the Windows API to check device capabilities is quite
limited, we now test additional common formats and add them to the
supported formats if the device can open them.
