Add simple-id-agent for wayland-ivi-extension 2.0.2

Add a subdirectory id-agent-modules for simple-id-agent.
And load this library in ivi-controller.
   
These codes are copy from this commit create by Emre Ucan.
This commit is from meta-agl and can not cherrypick to meta-agl-demo.
So copy it and create a new patch, change a litte line number to 0002.
