Currently, there is a hetero runtime property that darwinn
and other hetero runtime project will use: the trace level
(vendor.google.silicon.max_trace_level).
This change allows edgetpu services and clients to be able to see
that property in order to change the trace level.
Bug: 272292650
Test: verified it to build but not tested on device yet since selinux
has not been enforced yet.

The TPU cache coherency was set to false by default for testing/migration purposes. Now that the applications have been verified to work with TPU cache coherency, this CL changes the default behavior of TPU cache coherency to be enabled.

Test:
All child bugs in b/255828212. Speech, Camera, TPU internal tests.

The flag was added in ag/21062178.
After this CL, the flag is readable by all apps and all DarwiNN HALs.

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

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
