sdong c8b20d469d Make InternalKeyComparator not configurable (#10342) 
Summary:
InternalKeyComparator is an internal class which is a simple wrapper of Comparator. https://github.com/facebook/rocksdb/pull/8336 made Comparator customizeable. As a side effect, internal key comparator was made configurable too. This introduces overhead to this simple wrapper. For example, every InternalKeyComparator will have an std::vector attached to it, which consumes memory and possible allocation overhead too.
We remove InternalKeyComparator from being customizable by making InternalKeyComparator not a subclass of Comparator.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/10342

Test Plan: Run existing CI tests and make sure it doesn't fail
