implements data-url fetching
Fixes#10165
jdm mentioned of decoupling the, payload loading mechanism to data_loader.rs. So accordingly a `decoder` method has been added to data_loader.

Implement ::selection pseudo-element
It only supports `color` and `background`, for now, but it shouldn't be hard to add more properties (like text-shadow).

Add Http Global State Object
This adds a new HttpState object which holds common http state(#10175). This reduces the amount of work that is required to add extra things to the Http state.
The HttpState object currently holds:
```
hsts_list: Arc::new(RwLock::new(HSTSList::new())),
cookie_jar: Arc::new(RwLock::new(CookieStorage::new())),
auth_cache: Arc::new(RwLock::new(HashMap::new())),
```

Replace hsts_list, auth_cache, and cookie_jar with http_state
Reverted a few changes
Moved http_state back to factory
Removed unnecessary Arc
Removed Arc for http_state
Fix#10147: Correctly handle flag local_urls_only
In function Request::fetch_main, flag local_urls_only (if set)
should allow fetching local urls only. Before this change, the flag had
the inverse behaviour.
Fixes#10147.

Generalize the style structs
This allows geckolib to pass gecko style structs and have the style system write to them directly, provided we implement all the traits.

add auth cache to resources + set auth header from it if url does not have creds
initial attempt of
- in resource_thread.rs, define an HTTP authorization cache storage (username, password, URL) and instantiate it like the cookie_storage member (inside an Arc<Rwlock<>> value, to enable sharing it between threads)
- in modify_request_headers in http_loader.rs, implement the remaining pieces of step 12(13?) of the appropriate specification using this new authorization cache.

When fetching about:blank, response body should be the empty byte
sequence.
Spec: https://fetch.spec.whatwg.org/#concept-basic-fetch
Before this change, response body would be set to `ResponseBody::Empty`,
and then fetching would result in an infinite loop at step 19 in fn
`main_fetch` (methods.rs).
In function Request::fetch_main, flag local_urls_only (if set)
should allow fetching local urls only. Before this change, the flag had
the inverse behaviour.
Add Tests For Asynchronous Fetch Calls With Filtered Responses
I've added two tests using async_fetch intended to create filtered responses. I caught and fixed a bug where waiting for response.body to be completed would never pass for Opaque or OpaqueRedirect, since their response.body is always `Empty`.
As always, I'd appreciate review and feedback! I don't plan to write new tests, but I will gladly patch up any gaps in the current tests.
