Process setting to disable elements.json generation

https://redmine.teklia.com/issues/11528#note-14

Requires backend#1961 (closed)

The Process interface in src/types/process.ts should include the new skip_elements_json boolean flag. The ProcessCreate and ProcessStart interfaces in src/api/process.ts should also include this flag and make it optional.

Under the Advanced settings dropdown in src/views/Process/Configure.vue, a new Skip JSON element listing checkbox should be visible only for Workers processes. The checkbox's state should be synchronized with the process, both when retrieving it and updating it. The checkbox is disabled when the component is in read-only mode.
