Background: Darwinn Runtime team wants to use a cloud-based infra (Android Core Experiments) to push flags from server to device. The flags will be stored into android properties under the namespace: `persist.device_config.edgetpu_native`, which has a property context called `device_config_edgetpu_native_prop` as added by the other CL: https://android-review.git.corp.google.com/c/platform/system/sepolicy/+/2434232 Change: Allow EdgeTpu service to read device_config_edgetpu_native_prop Test: Verified EdgeTpu has access to read the property Bug: 243553703 Bug: 246401730 Change-Id: I19dca0e2d3008e36bdbca50f610810148a7e11dd
