IMPALA-15021: Remove duplicate tcmalloc.thread_cache_free_bytes metric
In IMPALA-14874, we introduced several tcmalloc metrics
including tcmalloc.current-total-thread-cache-bytes and
tcmalloc.thread-cache-free-bytes. These are actually the
same underlying metric, so this removes tcmalloc.thread-cache-free-bytes.
Testing:
- Ran core tests

> Priority: Minor
>
> In IMPALA-14874, we added additional gperftools TCMalloc metrics. This
> included both tcmalloc.current-total-thread-cache-bytes and
> tcmalloc.thread-cache-free-bytes, which map down to the gperftools metrics
> tcmalloc.current_total_thread_cache_bytes and
> tcmalloc.thread_cache_free_bytes respectively. Inside the gperftools code,
> these are actually the same counter, so we can remove one.
