android: camera_device: Return AE FPS range

Browse source 
The result metadata reports an arbitrary {30, 30} FPS range for the
AE algorithm.

The actual FPS range should be returned in the Request::metadata, but
as libcamera currently does not support that feature temporarily work
around the issue and return the FPS range requested by the camera
framework.
