Martin Robinson e7ee1171d8 script: Remove some proprietary Servo-only testing methods from Window (#42728)
These three methods date back from the very early history of Servo and
are no longer necessary:

1. `Window.debug`: `console.log` is a better replacement for this method
   now. A manual test that tests the very basics of JavaScript used
   this. This test is removed as well.
2. `Window.gc`: This can be replaced with `TestUtils.gc`, which is part
    of a W3C specification.
3. `Window.js_backtrace`: This method is moved to `ServoTestUtils`.

Testing: Tests are updated to reflect these changes.
