Hdr format settings [Backend]

Added new APIs to DisplayManager to set the user disabled HDR formats,
and get/set if user disabled formats should be ignored or not.
These new settings are stored in Settings.Global.
Modified the implementation of Display#getHdrCapabilities to not return
the formats disabled by user.
