Re-enable APM E2E tests and allow server to shut down cleanly on failure (#115450)

* Re-enable APM E2E tests and allow server to shut down cleanly on failure

Calling `process.exit` in the test script made it so the FTR runner would not properly shut down the server, and cause other tests to fail because Kibana was left running on a port. Remove that and just throw
instead.

No changes were made to the tests, as I was unable to reproduce any failures locally. I'll try in CI and see if we can get anything to fail.

Fixes #115280.
