Auto merge of #22420 - cdeler:enable-upstream-bluetooth-tests, r=jdm

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
