drm_hwcomposer: Implement getDisplayConfigurations

This deprecates calls like getDisplayConfigs and getDisplayAttribute.
Once HWC2 support has been removed from drm_hwcomposer, the legacy calls
could be implemented by calling getDisplayConfigurations.

The main different between the two is that in HWC3, the dpi is in
dots-per-inch and its unit is float. In HWC2, the dpi is in
dots-per-1000-inches and its unit is int32.
