Fix network event update Message (#37543)

- Add `ResourceArrayType` with `Available` and `Updated` variants
- Rename `resources-available` and `resource-available` to
`resources-array` ,`resource-array`
- Add `ResourceArrayType` as an argument to decide the type of resources
- Add `Option<ResponseContentMsg>`,`Option<ResponseStartMsg>`,
`Option<ResponseCookiesMsg>`,
`Option<ResponseHeadersMsg>`,`Option<RequestCookiesMsg>`,
`Option<RequestHeadersMsg>`, `total_time`, `security_state` to
`NetworkEventActor` struct , and serialize the data in each to
`resource_updates` , flattening the nested arrays into a single JSON
- Refactor the following methods `request_headers`,`response_start` ,
`response_content`,`response_cookies`,`response_headers`,
`request_cookies`,`total_time` to associated functions passing
`HttpRequest` and `HttpResponse` as parameters .

Testing: Ran servo with devtools flag to see the logs corresponding to
the changes
Fixes: https://github.com/servo/servo/issues/37479

This PR Builds on https://github.com/servo/servo/pull/37517 and was
opened due to merge conflicts and branch issues
