refactor(hidpi): enable HiDPI support if Qt supports it

Browse Source 
Previously HiDPI support is conditionally enabled based on compilation
parameters as well as environmental variables which makes binary
distribution difficult. This commit automatically enables runtime DPI
scaling if Qt supports it (version 5.6 and beyond).
