Fixed bug in textinput::adjust_vertical concerning selection_origin
<!-- Please describe your changes on the following line: -->
The `adjust_vertical` function of the `TextInput` module was forgetting to update the `selection_origin`.
I discovered the bug and figured out how it fix it using formal verification. More precisely, I manually translated the Rust code in a [F*](https://www.fstar-lang.org/) program that was functionally equivalent. Then I used the `assert_ok_selection` as a post-condition on the following functions :
* `select_all`
* `clear_selection`
* `adjust_selection_for_horizontal_change`
* `clear_selection_to_limit`
* `adjust_vertical`
* `perform_horizontal_adjustment`
* `adjust_horizontal`
* `adjust_horizontal_to_line_end`
I managed to prove automatically (using the Z3 backend of F*) that the post-condition held for all the functions except for `adjust_vertical`. I used the error messages from F* to infer the missing code so that the postcondition could hold and manually translated it to this PR diff.
I also added a simple unit test that would fail without this patch, and observed that the assertion failures noted in https://github.com/servo/servo/issues/22457 disappeared with this patch.
This verification work also allows me to say that the code of all the functions is now functionally correct in the sense that they all yield a valid selection in the sense of `asssert_ok_selection`, in all cases.

Enable upstream bluetooth tests
I enabled bluetooth WPT tests
But I'm still worry that a lot of tests failed (more than 150). I decreased them by
```
prefs: ["dom.bluetooth.enabled:true"]
```
But it's still a lot of failed tests

Initialize iframe viewport immediately
This is probably a significant cause of unstable test results, and it finally bothered me enough to fix it. The solution isn't great for performance (a sync layout query every time a iframe is added to a document), but performance needs to follow correctness.

Improve implementation of media resource fetch algorithm
I have been observing inconsistent behaviors with my local tests depending of the media asset being played. I figured that we had these issues:
- We were setting the player EOS as soon as we got the first [process_response_eof](1046ae58a1/components/script/dom/htmlmediaelement.rs (L1596)). This is fine only if there is a single request. But that's not the case for multiple range requests or for seeks. Setting the player EOS makes the player appsrc reject any new buffers, and that breaks playback. Figuring out when is the right time to set the player EOS won't be a straight forward task, so my suggested fix for now is to simply not set it for now. It is a cleanup step that it would be nice to have but it is not mandatory.
- We were setting the input size more than once for multiple range requests and with the incorrect value. The fix uses the `content-length` or the `content-range` headers for single and range requests respectively.
- We were moving to the HaveEnoughData state if a fetch request succeded but no data was fetched from the network.
