[codegen] relax memory ordering for metric updates
Since 'code_cache_hits' and 'code_cache_queries' are used as metric
gauges only and aren't consumed in any way that would require strong
consistency guarantees, it makes sense to switch from the
'memory_order_seq_cst' to the 'memory_order_relaxed' when updating
the underlying '{hit,query}_counter_' atomic counters.
