android: camera_device: Break-out request template

Browse source 
Currently the request template returned from
CameraDevice::constructDefaultRequestSettings() is the same for all
the supported template types.

To prepare to adjust the template depending on the use case, break out
the template generation to a dedicated function that supports the
PREVIEW use case. All the other template types use the
requestTemplatePreview() function and just update the capture intent
property.
