Add NNAPI traces to benchmark app

Add tracing so we can:
- Get the model name by adding Overall phase
- Match numbers between benchmark output and systrace by:
    - Adding Warmup and Benchmark phase traces
    - Adding Execution phase trace
    - Moving benchmark start time marker to match systrace's
      idea of Execution phase

Bug: 78137932
Bug: 78139001
