Convert KernelDestructionSubscriber to use configurators

I think the test fail means somehow the number of cache sets has been decreased in the standard profile?

    $this->assertGreaterThanOrEqual(59, $performance_data->getCacheSetCount());

This is now consistently 53. But no other tests fail, so I don't think anything is broken - is this just an accidental performance improvement?

📌 Investigate variable database query counts in performance tests Active

For the test failure.

Added some q's to MR

Looks like 📌 Allow needs_destruction services to run on page cache hits Needs review will make this obsolete, destroying the services in the kernel itself is a much better idea.

@arunkumark you've removed the code that sets up the configurator? The registerService method is no longer called by anything.

Still, I think this will be obsolete soon as per #8.

Postponing this on 📌 Allow needs_destruction services to run on page cache hits Needs review which removes this subscriber altogether and is RTBC.

📌 Allow needs_destruction services to run on page cache hits Needs review landed so we don't need to do this.
