Perfetto SDK: use external 'dev.perfetto.sdk' dependency.

We want to use the same Perfetto Java SDK code both for the 3P
users and in Framework,the same way we are already doing
for the Perfetto C API.

We add a dependency to the external java and jni code.
We guard the new usage with a flag `perfetto_sdk_tracing_v3`.
We will delete the android.os.PerfettoTrace code in the future.

I've updated the 'TracePerfTest' with a 'V3' test versions,
to make sure we have no perf regressions.
I've also add tests to make sure the 'V3' version init and works fine.

Test: atest TracePerfTest
