Subject: [PATCH] rabbit_misc: Generate a `NEW_PID_EXT`-based binary in
 compose_pid/4

The `creation` field might not fit into one byte which makes the
`PID_EXT` format unsuitable for this case.

The `NEW_PID_EXT` format is supported since Erlang 19.0, so it is safe
to always use it, no matter the value of `creation`, because RabbitMQ
3.7+ requires at least Erlang 19.3+.
