Add androidx.tracing dep as workaround for AGP bug

AGP has a bug which mistakenly downgrades this to an old version in test
scope which then causes the tests to fail due to a missing method.  As
mentioned in android/android-test#1755, this can be worked around by
explicitly specifying it as an implementation dependency.
