SnapdragonCamera: Adding support for any number of cameras in app.

At present the SnapdragonCamera App can support maximum of 2 cameras.
Generalizing SnapdragonCamera App to support any number of cameras
exposed to the application.

Note - If number of cameras supported is greater than 2 then we need
to add corresponding entries in media_profiles.xml so that recording
can work fine on more than 2 cameras supported.
