It should be easier to translate sizes in bytes to human-readable
strings consistently rather than having to repeat this code (and the
string translations) in various places. The FileDialog in QtQuick.Controls
has a use for this, too.
[ChangeLog][QtCore][QLocale] Added QLocale::formattedDataSize() for
formatting quantities of bytes as kB, MB, GB etc.
