Add SELinux policy for edgetpu_native device_config prop

The new android property namespace will store the configurations which are set on the server side and read by the EdgeTpu HAL.

Notes:
* This CL is similar to nnapi_native CL: https://android-review.git.corp.google.com/c/platform/system/sepolicy/+/1844919
* The read permission of EdgeTpu HAL will be added in another internal CL.
