[ui] Sort processes by number of perf samples When the user runs ./tools/cpu_profile -n <app>, there will be a process track group for every process on the system, but only one will actually contain the perf samples the user requested. Sort all processes by number of perf samples so that the process the user is likely most interested when doing CPU profiling will appear at the top and be easy to find. Testing: Collect a cpu profile using ./tools/cpu_profile -n <app> verify that the profiled app appears at the top after the trace is opened. Change-Id: Iaf2419ac6369baa5326a413b9e0612c502c91004
