Fix perfetto category registration order

In the tracinglib, a category is registered but sysui
perfetto registration hasn't happened yet. This leads
to a crash in the perfetto c sdk.

Ideally, the Java layer (or c layer) should avoid crashing
in this case. In the meantime, we call PerfettoTrace#register
right before Category#register. This could attempt perfetto
registration twice, but the second one will no-op.
