IMPALA-3342: Runtime profile TotalCpuTime should eliminate wait times

Impala uses the wall clock timer to measure the CPU time from the thread
start to finish. This also accounts for all the time when a thread gets
pre-empted or blocked. This change adds the CLOCK_THREAD_CPUTIME_ID timer to
measure the CPU time spent in execution only.
