Subject: android: camera_device: Calculate metadata size

As we move to have more and more dynamically generated static metadata
entries, the size of the metadata buffer has to be calculated
dynamically inspecting the information collected from the camera.

Provide a method to perform metadata buffers size calculation and
use it when generating camera static metadata.
