android: camera_device: Use AE FPS range in template

Browse source 
The request template returned by requestTemplatePreview() uses an
arbitrary {15, 30} Auto-Exposure algorithm FPS range. Use the one
calculated at static metadata creation time, which is consistent with
the camera limits.

Once template generation will be performed inspecting the requested
capture intent, the FPS range over which the AE algorithm can range
shall be tuned accordingly.
