Currently, there is a hetero runtime property that darwinn
and other hetero runtime project will use: the trace level

This change allows edgetpu services and clients to be able to see
that property in order to change the trace level.

because we need it for DarwinnDelegate to forcelly disable the cache coherency feature for debugging purpose. This sys prop should be readable by all Darwinn Delegate clients, but only modifiable by `adb root`.
Test: Verified that both camera app and camera HAL can read the flag. See pending CL cl/507001854 and android_flag_permission_test.md
