Remove Optional pipeline_id

<!-- Please describe your changes on the following line: -->
All code that creates a WorkerScriptLoadOrigin passes a Some value for the pipeline, so we should remove the Option from the struct member field.

I changed the `WorkerScriptLoadOrigin` struct in `components/script_traits/lib.rs` to have a PipelineId and not an Option<PipelineId>. In `components/script/dom/worker.rs` and `components/script/dom/serviceworkerregistration.rs` it was changed so that `WorkerScriptLoadOrigin` was instantiated with a non-Optional. In `components/script/dom/dedicatedworkerglobalscope.rs` testing for if pipeline_id is an Optional is removed.

In `components/script/dom/serviceworkerglobalscope.rs` and `components/script/dom/dedicatedworkerglobalscope.rs` a `PipelineId` was provided as an Optional to a `RequestBuilder` and I changed it to provide a `Some(pipeline_id)` instead. I am not sure changing the [RequestBuilder struct](5c3bda0251/components/net_traits/request.rs (L118-L159)) at line 147 to accept a non-optional was within this issue so I left it as is.

I was able to successfully build it so I assume these changes worked, however I am not sure about the implications of the changes made in the unsafe block in `components/script/dom/dedicatedworkerglobalscope.rs`.
