SystemUI: Import Pixel display interfaces 

We'll need the Pixel display interfaces to implement HBM control for
UDFPS, but they're in the hardware/google/interfaces namespace that we
can't import here. Add a copy of the display interfaces (as of
android-12.0.0_r13) until we have a better solution.

NB: setCompensationImageHandle(NativeHandle, String) has been removed
because NativeHandle is a HIDL type that isn't available in a pure-AIDL
context.
