Add the QStorageInfo class
Allows to retrieve information about mounted volumes such as label,
total/available size, filesystem type and so on.
Possible use cases are:
- allows to do checks about filesystem before performing actual
operation (such as available/maximum volume size)
- allows to retrive information about volume that can be shown in file
dialogs
- allows to retrieve volume for specific path and check if two or more
paths belong to the same volume or not
[ChangeLog][QtCore] Added QStorageInfo class to retrive information
about mounted volumes and drives
