Implement fetching physical QStorageInfo::blockSize() under Windows
This is implemented in two passes, first we try the older and
always available DeviceIoControl() function. This works most of
the time, though it might fail for example for storage devices
attached via USB. In this case, we try to dynamically load the
newer NtQueryVolumeInformationFile kernel function. Since this
is probably more expensive, we do this as fallback.
[ChangeLog][QtCore][QStorageInfo] The QStorageInfo::blockSize()
will now report the physical block size of a storage device under
Windows. Network mapped drives are not supported.
Fixes: QTBUG-93976
