Jetty 12: ISE thrown when server stopping with suspended request

[sbordet]

Jetty version(s)
12+

Jetty Environment
ee10

Description
Similar to #11016, the server throws ISE if an application is trying to send a response from Servlet.destroy(), but rather than using response.sendError(), it just normally set the status code via response.setStatus().

Note that in discussions with the servlet EG, it was not felt that it is necessary to support responses being able to be sent from destroy. We can still support that, but it is not required by the spec group.
