[9.2] (backport #18366) make queue_max_bytes a long again allowing queues bigger than 2GB

[mergify]

The queue factory setting "queueMaxBytes" used to be a long link:

long queueMaxBytes = RubyFixnum.num2long(args[6]);

But with the refactoring of #18180, it became an Integer by mistake:

.queueMaxBytes(getSetting(context, settings, QUEUE_MAX_BYTES).toJava(Integer.class))

Which prevents queues being bigger than 2^31-1, causing crashes to anyone setting their PQ to 2GB or more:

queue.max_bytes: 2147483647 # 2GB-1 OK
queue.max_bytes: 2147483648 # 2GB FAIL

This change makes queueMaxBytes a Long again, with a test confirming that queues larger than 2ˆ31-1 (max int) can be created.

Without this change the new test fails:

❯ bin/rspec logstash-core/spec/logstash/queue_factory_spec.rb
..F.
