Add Websocket task source
According to the doc: https://html.spec.whatwg.org/multipage/web-sockets.html#network
The task source for all tasks queued in the websocket section are the
websocket task source, so this commit also updates those references to
use the appropriate one.
Also, while working on this, I made a typo here: 5dd6e21c2e/components/script/dom/window.rs (L191)
Setting the name incorrectly. The error, however, was this:
```bash
error[E0412]: cannot find type `WebsocketEventTaskSource` in this scope
--> components/script/dom/window.rs:171:1
|
171 | #[dom_struct]
| ^^^^^^^^^^^^^ did you mean `WebsocketTaskSource`?
```
Which isn't useful at all. Not sure if it's a rustc problem or something related with htis code base, but I thought it was worth mentioning.
