core: use `malloc` instead of `region` allocator in procedure name cache

The procedure name cache uses a region for hash table entry allocation, but
the cache is a thread local variable, while the `region` uses a `slab`
allocator the lifetime of which is bounded by `main`, while thread locals
are destroyed after `main`: use the `malloc` allocator instead.

Benchmark from #7207 shows that this change does not effect performance.

Closes #8777
