camera: Add capability to limit zoom ratio in HWL

Framework mandate the zoom ratio range in concurrent mode to be at
least [1, maxDigitalZoom]. Each project may have different capabilities
and decide to extend the supported concurrent zoom ratio range up to the
complete zoom range.
Therefore the decision of adjusting zoom ratio regarding concurrent mode
should be done in HWL.
