Xinyi Zou 867f44d606 [opt](memory) jemalloc conf lg_tcache_max restore default #26362
tc/jemalloc_free_memory in web beip:8040/mem_tracker is the cache size of Jemalloc.

Previously lg_tcache_max:20, this will cache up to 1M Bin in the thread cache, which will cause the Jemalloc cache to be too large in some scenarios.

Restore the default lg_tcache_max:16, which can cache a maximum of 64K Bins.

If you are doing a performance POC, you can consider increasing it.
