IFingerprintInscreen: Allow HALs to control dimming
* On OnePlus 7 Pro, the kernel provides the dimming value. We can use
hals to directly retrieve that value instead of calculating manually.
* Also, the kernel implemented brightness boosting. Allow the hal to
pass this information to the framework so no repeated boosting is done.
